Herein we report the scalable synthesis of Co/N-codoped porous carbon (Co/N-C) catalysts by pyrolyzing poly (Schiff base)/Co(II) complex. The strong Co(II)-binding affinity of poly(Schiff base) leads to the formation of uniformly distributed Co(0) nanoparticles, Co-N-x species, and N-C configurations, in which their catalytic contributions are confirmed and estimated by ligand-poisoning and acid-etching experiments and the Co-N-x species has been proved to be highly active for catalytic transfer hydrogenation (CTH) reaction. Consequently, the as-prepared Co-N/C-950 catalyst exhibits an ultrahigh activity for the CTH of 4-nitrophenol (4-NP) with a TOF of 226 mol(4-NP) mol(Co)(-1) min(-1) (13560 h(-1)) together with an excellent selectivity for CTH of challenging nitroarenes. Moreover, the Co(0) nanoparticles embedded in the Co-N/C-950 catalyst can be further transformed to Co4N phase by a facile nitridation reaction, yielding Co4N-N/C-950 catalyst with even higher activity for the CTH of 4-NP (TOF up to 310 mol(4-NP) mol(Co)(-1) min(-1)).

Although alkynes have been extensively exploited in [2 + 2 + 2] cycloadditions with nitriles to form N-heterocyclic aromatics, the alkyne-like metal carbon triple bond has never been used in [2 + 2 + 2] cycloadditions with nitriles. We demonstrate the synthesis of the first metallapyrazine through [2 + 2 + 2] cycloaddition reactions of a metal carbyne complex with nitriles. Experimental observations and density functional theory calculations are evidence for the aromatic character of the metallapentalenopyrazine.

A quantitative Lewis acidity/basicity scale toward boron-centered Lewis acids has been developed based on a set of 90 experimental equilibrium constants for the reactions of triarylboranes with various O-, N-, S-, and P-centered Lewis bases in dichloromethane at 20 degrees C. Analysis with the linear free energy relationship log K-B=LA(B)+LBB allows equilibrium constants, K-B, to be calculated for any type of borane/Lewis base combination through the sum of two descriptors, one for Lewis acidity (LA(B)) and one for Lewis basicity (LBB). The resulting Lewis acidity/basicity scale is independent of fixed reference acids/bases and valid for various types of trivalent boron-centered Lewis acids. It is demonstrated that the newly developed Lewis acidity/basicity scale is easily extendable through linear relationships with quantum-chemically calculated or common physical-organic descriptors and known thermodynamic data (Delta HBF3 ). Furthermore, this experimental platform can be utilized for the rational development of borane-catalyzed reactions.

An efficient one pot strategy has been developed for the synthesis of 2-acylbenzothiazoles and quinoxalines from aryl methyl ketones. A variety of heterocycles of these two categories could be prepared in a two-step sequence in excellent yields. The reaction was performed starting from aromatic ketones via an aryl gloxal intermediate which, on further condensation with 2-aminobenzenethiol or o-phenylenediamine, produces the corresponding heterocyclic skeleton. Aromatic ketones are initially treated with TsNBr2 in DMSO at 65 degrees C for 3 h and the crude reaction mixture was treated with 2-aminobenzenethiol (at 80 degrees C) or o-phenylenediamine (at RT) to generate the final compound.

New insight is provided into the chemistry of 12 para-substituted nitrobenzene compounds, using the high-level computational method G3(MP2) and DFT methods. The results show that the chemical properties of the nitrobenzene molecules, such as reduction potential, ionization energy, proton affinity, pK(a), interaction energy of the fragments, hyperpolarizability, exaltation index, band gap, UV electron excitation, and QTAIM properties, are controlled by the strong coupling between the nitro group (NO2) and the nature of the various para-substituents via the benzene ring as their conducting link. As the electron donating tendency of the para-substituent increases in the molecules, the electron cloud around the nitro group also increases, resulting in contraction of the N-C bonds and elongation of the N=O bonds, consequently leading to gradually increasing electron conductivity, polarizability, and ionization energy but lower proton affinity, thereby progressively impeding the reduction potential of the molecules. The experimental reduction potential was reproduced to a high degree of accuracy, with a mean absolute deviation (MAD) of 0.048V, depending on the computational method used and the choice of the free energy circle. Additionally, the experimental electron affinity and proton affinity of the 12 molecules were reproduced to a high degree of accuracy.

An iridium-catalyzed transfer hydrogenation of N-heteroarenes to access a series of substituted 1,2,3,4-tetrahydroquinoline derivatives in excellent yields is disclosed. This transformation is distinguished with water-soluble and air-stable iridium complexes as the catalyst, formic acid as the hydrogen source, mild reaction conditions, and broad functional group compatibility. Most importantly, a tentative chiral N,N-chelated Cp*Ir(III) complex-catalyzed enantioselective transfer hydrogenation is also presented, affording chiral products in excellent yields and good enantioselectivities.

Designing and fabricating catalysts with highly dispersed metal nanoclusters (NCs) is very crucial for achieving high activity and selectivity. In this work, all-alkynyl-protected [Ag-74(C CPh)(44)](NO3)(2) cluster (Ag duster) with a well-defined structure was firstly intercalated in alpha-zirconium phosphate (alpha-ZrP) through ion-exchange. Then the atomically precise Ag cluster can be immobilized robustly in the support by a sequential process of carbonization, calcination and reduction. The supported Ag duster showed the relatively high catalytic activity (TOP = 222.9-445.8 h(-1)) and excellent recyclability for hydrogenation of a variety of nitroaromatics, as well as the compounds with carbon-carbon double bonds even if the loading of Ag was as low as 0.72 wt.%. Zirconium pyrophosphate acts as not only a stabilizer of Ag duster through a spatial confinement, but also an adsorption site for nitroaromatics. The residual carbon arisen from thermal decomposition of all-alkynyl ligand coordinating on Ag cluster exerted an important role in protecting Ag duster from sintering. As a result, the intercalation of Ag cluster in the interlayer region is a promising strategy for extending their potential applications in catalysis.

A titanium.IV) oxide photocatalyst modified with 2,3-dihydroxynaphthalene (DHN/TiO2) responds to visible light, and electrons are photogenerated to the conduction band of TiO2 under light irradiation in the presence of a suitable hole scavenger. The reducing potential of DHN/TiO2 was applied for photocatalytic conversion of a nitro group to an amino group of aromatics having other reducible groups under hydrogenfree and noble metal-free conditions at room temperature. Various nitro aromatics having vinyl, chloro, bromo, and acetyl groups were converted to amino aromatics with high yields with the reducible groups being preserved. Some parameters affecting the catalytic performance were investigated, and the reaction rate was almost determined by the amount of the substrate adsorbed on DHN/TiO2.

On water catalytic aldol reaction catalyzed by polyetheramine (D230) has been developed for easy access to 3-substituted 3-hydroxyindolin-2-ones through the reaction between various substituted isatins and acetophenones/cyclic ketones in high yields under room temperature. Systematic mechanism investigation uncovers the secret for the on water catalytic aldol reaction: comparison of the heterogeneous and homogeneous reaction circumstances with yields of 95 and 20%, respectively, indicates the on-water reaction dominating; interfacial hydrogen bonding between isatin with H2O is tested based on the downfield shift of the C2 and C3’s C-13 NMR signals when water was added to the CDCl3 solution of isatin; Lewis base polyetheramine D230 catalyzes the aldol reaction via the enamine mechanism verified by in situ NMR and ESI-MS analysis.
