The iridium complex1based on a metalated CNP ligand containing an imidazolin-2-ylidene fragment has been prepared by treatment of the ligand precursor4with Ag2O followed by reaction with [IrCl(COE)(2)](2). The chlorohydride imidazolidin-2-ylidene complex6, which is isostructural to1, was synthetized by reaction of the previously reported dihydride derivative3with CH2Cl2. Complexes1and6exhibit luminescence arising from a(3)MLCT/ILCT state involving the metalated CNP ligand, which is particularly intense for1in the solid state at 298 K. Furthermore, the reactivity of complexes1and6towards bases was compared. Deprotonation of1with KOtBu produced the selective formation of the dinuclear complex7; meanwhile, the reaction of6led to a complex mixture of products. The same reactions carried out in the presence of PPh(3)produced the selective deprotonation of the P-bonded methylene bridges of1and6, yielding the isostructural derivatives9and10. DFT calculations performed on theuNHC-containing tautomersIandII, and thesNHC-based isomersIIIandIV, showed that the NHC-deprotonated derivativesIIandIVare more stable by 3.20 and 2.73 kcal mol(-1), respectively, than their P-deprotonated counterparts (IandIII). However, a reverse stability order was observed for hexacoordinated tautomersI center dot LandII center dot L, andIII center dot LandIV center dot L(L = PPh3, CO, MeCN). Finally, the catalytic activity of complex3in the transfer hydrogenation of ketones has been assessed.

The transformation of alkyl nitriles to symmetrical and asymmetrical secondary aliphatic amines promoted by the hexahydride complex OsH6 ((PPr3)-Pr-i)(2) (1) is described, and the mechanisms of the reactions involved are established. Complex 1 catalyzes the aforementioned transformations of aryl-, pyridyl-, and alkoxy-functionalized alkyl nitriles with linear or branched chains. The formation of the secondary amines involves primary imines, primary amines, and secondary imines as organic intermediates. The reactions take place under mild conditions (toluene, 100 degrees C, and 4 bar of H-2). Stoichiometric reactions of 1 with pivalonitrile and 2-methoxyacetonitrile have allowed us to isolate the trihydride azavinylidene derivatives OsH3{=N=CHR}((PPr3)-Pr-i)(2) (R = Bu-t (3), CH2OMe (4)). Their formation involves the insertion of the N-C triple bond of the substrates into an Os-H bond of the unsaturated tetrahydride OsH4 ((PPr3)-Pr-i)(2) (A), which is generated by reductive elimination of H-2 from the hexahydride precursor. The reaction of these trihydride azavinylidene species with H-2 is the key step for the reduction of the N-C triple bond of the nitriles. In the absence of H-2, the attack of A to the azavinylidene ligand produces the rupture of its C(sp(2))-C(sp(3)) bond. As a consequence of this attack and the presence of primary imines and amines in the reaction media, the binuclear complexes ((PPr3)-Pr-i)(2) H4Os(mu-CN)OsH3{kappa(1)-N-(NH= CHCH2OMe)}((PPr3)-Pr-i)(2) (5) and ((PPr3)-Pr-i)(2)H4Os(mu-CN)OsH3{kappa(1)-N-(NH2CH2CH2OMe)}((PPr3)-Pr-i)(2) (6) have been isolated and characterized by X-ray diffraction analysis, for 2-methoxyacetonitrile. DFT calculations reveal noticeable similarities between the hydrogenations of nitriles to primary imines and those of primary imines to primary amines.

A novel and rapid approach to characterise the occurrence of contaminants of emerging concern (CECs) in river water is presented using multi-residue targeted analysis and machine learning-assisted in silico suspect screening of passive sampler extracts. Passive samplers (Chemcatcher (R)) configured with hydrophilic-lipophilic balanced (HLB) sorbents were deployed in the Central London region of the tidal River Thames (UK) catchment in winter and summer campaigns in 2018 and 2019. Extracts were analysed by; (a) a rapid 5.5 min direct injection targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for 164 CECs and (b) a full-scan LC coupled to quadrupole time of flight mass spectrometry (QTOF-MS) method using data-independent acquisition over 15 min. From targeted analysis of grab water samples, a total of 33 pharmaceuticals, illicit drugs, drug metabolites, personal care products and pesticides (including several EU Watch-List chemicals) were identified, and mean concentrations determined at 40 +/- 37 ng L-1. For targeted analysis of passive sampler extracts, 65 unique compounds were detected with differences observed between summer and winter campaigns. For suspect screening, 59 additional compounds were shortlisted based on mass spectral database matching, followed by machine learning-assisted retention time prediction. Many of these included additional pharmaceuticals and pesticides, but also new metabolites and industrial chemicals. The novelty in this approach lies in the convenience of using passive samplers together with machine learning-assisted chemical analysis methods for rapid, time-integrated catchment monitoring of CECs.

A series of novel chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) were designed, synthesized and their structures were confirmed by H-1 NMR, C-13 NMR and mass spectral data. Further, all derivatives were tested for their anticancer activities against five human cancer cell lines such as MCF-7 (breast cancer), A-549 (lung cancer), Colo-205 (colon cancer), A2780 (ovarian cancer) and DU-145 (prostate cancer) by employing MIT assay. The clinically used drug etoposide was used as standard reference and the anticancer activity was expressed as the IC50 in mu M. Among the ten compounds examined compounds, 10b, 10c, 10d, 10h, and 10i possessed more promising anticancer activity. A molecular docking study implying ATR kinase was carried out to observe the binding mode of chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) on the active site of ATR kinase. The most promising compound, 10h showed pi – pi stacking interaction of trimethoxy phenyl and pyridone moiety with the residue Trp850, while the carbonyl (alpha,beta-unsaturated carbonyl) and methoxy functions showed H-bond interaction with the residue Ser773 and Thr856 respectively.

In this research, a novel, biodegradable and environmentally friendly catalyst composed of nickel nanoparticles supported on DNA was prepared and fully characterized by Fourier transform infrared spectroscopy, high resolution transmission electron microscopy, energy-dispersive X-ray analysis, X-ray photoelectron spectroscopy, UV-vis spectroscopy, inductively coupled plasma optical emission spectroscopy, and elemental analysis. The catalyst exhibited remarkable catalytic activity and chemoselectivity for the reduction of various substituted nitroarenes with sodium borohydride (NaBH4) as the source of inexpensive hydride in water at room temperature. High turnover frequency and selectivity were observed for the reduction of all tested substrates. Interestingly, the catalyst could be recovered conveniently for multiple recycling reactions with sustained activity. Furthermore, nearly no nickel species was leached out from the catalyst during the course of reaction, proving the true heterogeneity in the present catalytic protocol.Graphical AbstractThe reduction of various nitroaromatic compounds into their corresponding amines is achieved by DNA supported nickel nanoparticles with the sodium borohydride as the reducing agent in water at room temperature.

Infectious diseases are one of the common problems encountered globally. Even though there are a number of drugs available in the market for the treatment of infectious diseases, still many new molecules are required due to the problems with the existing drugs. Hence we prepared a series of chalcones (Al-A10) containing nitrophenyl moieties by Claisen-Schmidt condensation reaction. All the ten compounds were characterized by IR, NMR, Mass spectroscopy and elemental analysis. The compounds were further screened for antitubercular activity employing MABA assay and antibacterial and antifungal activities by cup plate method against selected tubercular, bacterial and fungal organisms. The compound A9 displayed potent antitubercular activity with MIC 11.02 +/- 0.030, whereas the compound A3 showed superior antibacterial and antifungal activities. Further, molecular docking studies were performed on Thymidine Kinase (TMP) of Mycobacterium tuberculosis by employing AU autodocker. The docking scores were in association with the in vitro MABA results and also identified the potent nature of A9 with the docking score -6.7. This study helped to identify novel nitrophenyl derivatives against thymidylate kinase.

A series of p-cymene and cyclopentadienyl Ru(II)-aNHC complexes were synthesized from 2-methylimidazolium salts with either an N-bound alkenyl (1, 3) or picolyl tether (6, 7). The C(5)-Me substituted alkenyl-tethered analogues (2, 4) were also synthesized. Ag-mediated C(2)-dealkylation was a prominent side reaction that led to the formation of normally bound NHC Ru(II) complexes, which in selected cases were isolated (5, 8). A C(4)- over C(2)-selectivity for ruthenium binding was established by protecting the C(2)-position with an iPr group on the imidazolium precursor, for which unique p-cymene (9) and cyclopentadienyl (10) Ru(II)-aNHC derivatives were synthesized. All complexes were applied in the transfer hydrogenation of ketones and in secondary alcohol oxidation, with higher catalytic activity for the p-cymene over the cyclopentadienyl systems, as well as the alkenyl- over the picolyl-containing aNHC complexes.

Herein, N,S-codoped carbon materials embedded with ultrafine and well-distributed Co nanoparticles (1.14 wt % Co) were prepared through pyrolysis of the hybrids of SNW-1 and Co(Ac)(2) coated with glucose. It was observed by TEM and XRD that Co nanoparticles (NPs) were entrapped in doped carbon shells uniformly. The glucose coating presented a significant impact on the size distribution of Co NPs and doped modes of heteroatoms, especially the S species. The catalyst displayed outstanding activity for catalytic transfer hydrogenation (CTH) with formic acid under the base-free system. Encouragingly, diverse secondary amines were produced in excellent yields through the domino reaction of hydrogenation and reductive amination. Remarkably, the catalyst with ultrafine Co NPs showed good durability under harsh reaction conditions and displayed no significant loss in both activity and selectivity in 5 runs. This was attributed to the protection of constructed N,S dual-doped carbon shells. Hence, we offer an alternative strategy for the construction of dual-doped carbon materials trapped with ultrafine transition metal, which can be further applied in various catalytic processes.

The high-valent molybdenum(VI) N-heterocyclic carbene complexes, (NHC)MoO2 (1) and (NHC)MoO(N+Bu) (2) (NHC = 1,3-bis(3,5-di-tert-butyl-2-phenolato)-benzimidazol-2-ylidene), are investigated toward their catalytic potential in the deoxygenation of nitroarenes. Using pinacol as the sacrificial and green reductant, both complexes are shown to be very active (pre)catalysts for this transformation allowing a reduction of the catalyst loading down to 0.25 mol %. Mechanistic investigations show mu-oxo bridged molybdenum(V) complexes [(NHC)MoO](2)O (4) and [(NHC)Mo((NBu)-Bu-t)](2)O (5) as well as zwitterionic pinacolate benzimidazolium complex 6, with a doubly protonated NHC ligand, to be potentially active species in the catalytic cycle. Both 4 and 5 can be prepared independently by the deoxygenation of 1 and 2 using triethyl phosphine (PEt3) or triphenyl phosphine (PPh3) and were shown to exhibit an unusual multireferenced ground state with a very small singlet-triplet gap at room temperature. Computational studies show that the spin state plays an unneglectable role in the catalytic process, efficiently lowering the reaction barrier of the deoxygenation step. Mechanistic details, putting special emphasis on the fate of the catalyst will be presented and potential routes how nitroarene reduction is facilitated are evaluated.
