Reference of 5,5′-Dimethyl-2,2′-bipyridine. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Boosting Photocatalytic Activities for Organic Transformations through Merging Photocatalyst and Transition-Metal Catalyst in Flexible Polymers. Author is Pan, Yao; Zhang, Nan; Liu, Chun-Hua; Fan, Shilu; Guo, Song; Zhang, Zhi-Ming; Zhu, Yuan-Yuan.

The merger of photocatalysis and transition-metal catalysis is of particular interest to develop useful and challenging synthetic methodologies. The catalytic activities of conventional dual-catalytic systems, however, are limited by the low synergistic efficiency between discrete catalytic centers due to their long average distance in solution Herein we carefully decorated Ir(III) photosensitizers and Ni(II) transition-metal catalyst into flexible polymers to afford two polymer-supported dual catalysts (P1-Ni and P2-Ni). These polyelectrolyte-type metallopolymers assembled into spherical polymer particles in some polar solvents. Their unique mol. and assembled structure contributed to shortening the distance between catalytic centers and increasing the local catalysts′ concentration within the catalyst, thereby greatly facilitating their electron, energy, and organic radical transfers during the catalytic cycles. The enhanced energy interaction and matched redox potential between two catalytic centers within the polymer were confirmed by steady- and transient-state luminescent spectra and cyclic voltammetry. These features enable them in catalyzing challenging organic transformations that involve efficiently incorporated photocatalytic and transition-metal catalytic cycles. We demonstrated that these two catalysts were highly effective in catalyzing C-S cross-coupling, C-O functionalized, C-N cross-coupling, and C-C cross-coupling reactions with broad substrate scopes and low catalyst loadings with turnover numbers of ~3100, ~1500, ~1400, and ~500, resp. This work provides a general methodol. to merge photosensitizer and transition-metal catalyst in a flexible polymer for significantly boosting the catalytic activity.

To contribute a solution for the global warming problem, the selective electrochem. reduction of CO2 to CO was studied in the gas phase using a [CO2(g), Co-N-C cathode | Nafion-H | Pt/C anode, H2/water] system without using carbonate solutions The Co-N-C electrocatalysts were synthesized by partial pyrolysis of precursors in inert gas, which were prepared from various N-bidentate ligands, Co(NO3)2, and Ketjenblack (KB). The most active electrocatalyst was Co-(4,4′-dimethyl-2,2′-bipyridine)/KB pyrolyzed at 673 K, denoted Co-4,4′-dmbpy/KB(673K). A high performance of CO formation (331 μmol h-1 cm-2, 217 TOF h-1) at 0.020 A cm-2 with 78% current efficiency was obtained at -0.75 V (SHE) and 273 K under strong acidic conditions of Nafion-H. Characterization studies using extended X-ray absorption fine structure (EXAFS), XPS, transmission electron microscopy-energy-dispersive X-ray (TEM-EDX), X-ray diffraction (XRD), and temperature-programmed desorption with mass spectrometry (TPD-MS) indicated the active site as Co coordinated with four N atoms bonding the surface of KB, abbreviated Co-N4-Cx structure. A model of the reduction mechanism of CO2 on the active site was proposed.

Compounds from the 2,2′-bipyridine mol. family were investigated for use as redox-active materials in organic flow batteries. For 156 2,2′-bipyridine derivatives reported in the academic literature, we calculated the redox potential, the pKa for the second deprotonation reaction, and the solubility in aqueous solutions Using exptl. data on a small subset of derivatives, we were able to calibrate our calculations We find that functionalization with electron-withdrawing groups leads to an increase of the redox potential and to an increase of the mol. acidity (as expressed in a reduction of the pKa value for the second deprotonation step). Furthermore, calculations of solubility in water indicate that some of the studied derivatives have adequate solubility for flow battery applications. Based on an anal. of the physico-chem. properties of the 156 studied compounds, we down-select five mols. with carbonyl- and nitro-based functional groups, whose parameters are especially promising for potential applications as neg. redox-active materials in organic flow batteries.

Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Supramolecular architectures of mononuclear nickel(II) and homobinuclear copper(II) complexes with the 5,5′-dimethyl-2,2′-bipyridine ligand: Syntheses, crystal structures and Hirshfeld surface analyses.

Two new compounds based on one mononuclear nickel(II) and one homobinuclear copper(II) complexes resp. and of general formula [Ni(dmbpy)2(CH3COO)]ClO4 (1) and [Cu2(dmbpy)2(CH3COO)3]ClO4 (2) with dmbpy = 5,5′-dimethyl-2,2′-bipyridine, were synthesized by hydrothermal treatment. Both were influenced by the coordinated acetate ion mol. The crystal and mol. structures of (1) and (2) were determined by single crystal x-ray diffraction method and both compounds were addnl. characterized by elemental and TGA, FTIR spectroscopy, powder X-ray diffraction and UV-visible. The mononuclear complex (1) shows a distorted octahedral geometry around the metal ion. However, the copper(II) compound crystallizes as an homobinuclear system, in which each of the metal ions is located into the N2O3 coordination spheres adopting a distorted square pyramidal geometry. In (2) the intramol. distance between two copper atoms is of the order of Cu1-Cu2 = 3.38(2) Å.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5,5′-Dimethyl-2,2′-bipyridine(SMILESS: CC1=CN=C(C=C1)C1=NC=C(C)C=C1,cas:1762-34-1) is researched.Reference of 5,5′-Dimethyl-2,2′-bipyridine. The article 《CO2 to CO: Photo- and Electrocatalytic Conversion Based on Re(I) Bis-Arene Frameworks: Synergisms Between Catalytic Subunits》 in relation to this compound, is published in Helvetica Chimica Acta. Let’s take a look at the latest research on this compound (cas:1762-34-1).

Reduction of CO2 to CO and H2O is a two electron/two proton process. For this process, multinuclear complexes offer advantages by concentrating reduction equivalent more efficiently than mononuclear systems. We present novel complexes with [Re(η6-C6H6)2]+ as scaffold conjugated to one or two catalytically active [Ru(dmbpy)(CO)2Cl2] subunits (dmbpy=5,5′-dimethyl-2,2′-bipyridine). The [Re(η6-C6H6)2]+ scaffold was chosen due to its very high photo- and chem. stability, as well as the multiple degrees of freedom it offers for any conjugated functionalities. High efficiency and selectivity for the reduction of CO2 to CO (over H2 or HCOOH) is reported. TONs and TOFs were found to be comparable or higher than for the catalyst subunit without the rhenium framework. Cooperativity in photo- and electrocatalysis is observed for the complex comprising two catalytic subunits. The synergistic communication between the two catalytic subunits is responsible for the observed enhancement in both photo- and electrocatalytic performance. Confirmation of electronic communication between the two [Ru(dmbpy)(CO)2Cl2] subunits as well as the elucidation of a possible mechanism was supported by electrochem., IR-spectroelectrochem. and DFT studies.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Mixed ligand copper(II) chelates derived from an O, N, S- donor tridentate thiosemicarbazone: Synthesis, spectral aspects, FMO, and NBO analysis, published in 2020-10-01, which mentions a compound: 1762-34-1, Name is 5,5′-Dimethyl-2,2′-bipyridine, Molecular C12H12N2, Reference of 5,5′-Dimethyl-2,2′-bipyridine.

Five new copper(II) chelates [(Cu(bmct))2] (1), [Cu(bmct)(phen)] (2), [Cu(bmct)(bipy)] (3), [Cu(bmct)(4,4′-dmbipy)] (4) and [Cu(bmct)(5,5′-dmbipy)] (5) with 5-bromo-3-methoxysalicylaldehyde-N(4)-cyclohexylthiosemicarbazone (H2bmct) as the chelating ligand and 1,10-phenanthroline, 2,2′-bipyridine, 4,4′-dimethylbipyridine, 5,5′-dimethylbipyridine as coligands were synthesized and characterized by different physicochem. techniques like CHNS anal., molar conductivity and magnetic studies, IR, UV/Vis and EPR spectral studies. In all the complexes, the thiosemicarbazone exists in thioiminolate form and coordinates to the metal through azomethine nitrogen, thioiminolate sulfur, and phenolate oxygen. EPR spectra in polycrystalline state at 298 K showed that compounds 1, 4, and 5 are isotropic, 2 is axial and 3 is rhombic in nature. In DMF at 77 K, compound 1 showed hyperfine lines in the parallel and perpendicular regions as well as superhyperfine lines due to the interaction of copper center with azomethine nitrogen of the ligand. Complex 2, in which g-II > g ⊥> 2.0023 suggests a distorted square pyramidal structure. To analyze the stability of the complexes, quantum chem. parameters like hardness, softness, polarizability, electrophilicity, electronegativity, and dipole moment were calculated and discussed within the framework of electronic structure principles known as Maximum Hardness, Min. Polarizability and Min. Electrophilicity Principles. Besides, the intramol. donor-acceptor interactions for all complexes were evaluated by using NBO anal. All calculations proved that compound 3 is the most stable chelate among them.

Author is Kaczmarek, Anna M.; Van Der Voort, Pascal.

In this work authors introduce the use of nano-sized (50-70 nm) lanthanide-grafted periodic mesoporous organosilicas for both metal ion sensing and solvent sensing. For this study a PMO constructed from the N,N-bis(trimethoxysilylpropyl)-2,6-pyridine dicarboxamide linker and tetra-Et orthosilicate (at a 5 : 95 ratio) was employed. This material was grafted with Eu3+, Tb3+ or a mixture of Eu3+-Tb3+ chloride salts to obtain strongly emitting nano-sized luminescence materials. To further enhance the luminescence properties of the materials two different co-ligands were used – 1,10-phenanthroline (phen) and 5,5′-dimethyl-2,2′-dipyridyl (bpy). The luminescence properties of the developed series of hybrid materials were studied in detail in the solid-state and after dispersing in water. The materials were investigated for their use as ion sensors, with the Eu3+ and Tb3+ phen and bpy co-grafted materials showing selective “”turn on”” fluorescence for Pb2+ and Cr3+ ions (at a 10 ppm concentration of the ions). The Eu3+-Tb3+ co-grafted materials showed solvatochromism and could be used as a solvent sensor to distinguish between protic and aprotic solvents.

Category: benzodioxans. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Exploiting the versatility of pyridyl ligands for the preparation of diorganotin (IV) adducts: spectral, crystallographic and Hirshfeld surface analysis studies. Author is Momeni, Badri Z.; Fathi, Nastaran; Abbasi, Reyhaneh; Janczak, Jan.

Diorganotin (IV) complexes SnR2X2 (R = Me, Ph; X = Cl, NCS) form a series of versatile complexes when react with bidentate substituted pyridyl ligands. The reaction of dimethyltin dichloride with 5,5′-dimethyl-2,2′-bipyridine (5,5′-Me2bpy) resulted in the formation of [SnMe2Cl2(5,5′-Me2bpy)] (1). Moreover, the reaction of SnMe2(NSC)2 with 4,4′-di-tert-butyl-2,2′-bipyridine (bu2bpy), 1,10-phenanthroline (phen) and 4,7-diphenyl-1,10-phenanthroline (bphen) affords the hexa-coordinated complexes [SnMe2(NCS)2(bu2bpy)] (2), [SnMe2(NCS)2(phen)] (3) and [SnMe2(NCS)2(bphen)] (4), resp. The resulting complexes have been characterized using elemental anal., IR, multinuclear NMR (1H, 13C, 119Sn) and DEPT-135° NMR spectroscopy. On the other hand, the reaction of diphenyltin dichloride with 2,2′-biquinoline (biq) and 4,7-phenantroline (4,7-phen) led to the formation of polymeric complexes of [SnPh2Cl2(4,7-phen)]n (5) and [SnPh2Cl2(biq)]n (6). The NMR spectra, however, reveal the ligand lability in solution and suggest a coordination number of 5. The X-ray crystal structures of complexes [SnMe2Cl2(5,5′-Me2bpy)] (1), [SnMe2(NCS)2(bu2bpy)] (2) and [SnMe2(NCS)2(bphen)] (4) have been determined which reveal that the geometry around the tin atom is distorted octahedral with trans-[SnMe2] configuration. Interestingly, the crystal structure of (H2biq)2[SnPh2Cl4]•2CHCl3 (7) was characterized by X-ray crystallog. from a chloroform solution of [SnPh2Cl2(biq)]n (6) indicating the formation of doubly protonated [H2biq]+ and [Ph2SnCl4]2- which are stabilized by a network of hydrogen bonds with a feature of trans-[SnPh2]. The 3D Hirshfeld surface anal. and 2D fingerprint maps were used for quant. mapping out of the intermol. interactions for 1, 2, 4 and 7 which show the presence of π-π and hydrogen bonding interactions which are associated between donor and acceptor atoms (N, S, Cl) in the solid state.
