Authors report a radical-based organocatalytic method for the direct benzylation of allylic C-H bonds. The process uses nonfunctionalized allylic substrates and readily available benzyl radical precursors and is driven by visible light. Crucial was the identification of a dithiophosphoric acid that performs two distinct catalytic roles, sequentially acting as a catalytic donor for the formation of photoactive electron donor-acceptor (EDA) complexes and then as a hydrogen atom abstractor. By mastering these orthogonal radical generation paths, the organic catalyst enables the formation of benzylic and allylic radicals, resp., to then govern their selective coupling. The protocol was also used to design a three-component radical process, which increased the synthetic potential of the chem.

A combined system involving Er(III)-based chiral Lewis acid catalysis, Ir(III)-based photoredox catalysis, and bromide-radical-mediated hydrogen atom transfer was disclosed. The introduction of a bulky and nonredox chiral Lewis acid through the photoredox pathway enabled the radical addition process and inhibited the above competitive reactions. The visible-light-promoted catalytic asym. alkylation of heteroaryl-based ketones with diverse hydrocarbons (mainly benzyl) delivered a variety of congested enantioenriched tertiary alcs.

The direct oxidation of C-H bonds in organic materials into necessary oxygen containing compounds under mild conditions has attracted increasing attention. A Keggin type polyoxometalate based metal organic complex (MOC), [CuII4CuI(H2trz)4(C2O4)(H2O)4(H3PW11.18CuII0.82O40)]·8H2O (1) (H3trz = 1,2,4-triazole), was designed and synthesized under hydrothermal conditions, and was structurally characterized by single crystal X-ray diffraction, PXRD, IR spectroscopy, TGA, and XPS. Complex 1 is a 3D 4,6,8-connected architecture derived from [Cu5(H2trz)4(C2O4)2(H2O)2]n units and [PW11.18Cu0.82O40]6- anions, which can catalytically oxidize various types of alkylbenzenes. Gas chromatog. anal. showed that complex 1 as a heterogeneous catalyst could effectively catalyze the oxidation of diphenylmethane with 93% conversion and 99% selectivity within 6 h. In addition, the conversion for the catalytic oxidation of ethylbenzene was 96% with 99% selectivity. Compared with some reported catalysts, complex 1 exhibited a better catalytic effect and lower reaction time. Meanwhile, the catalytic oxidation of other benzyl derivatives with complex 1 was also investigated, which indicated that complex 1 possessed excellent catalytic performance.

A convenient asym. reductive amination of benzylic ketones (α-arylated ketones) catalyzed by newly designed Cp*Ir complexes bearing a chiral N-(2-picolyl)sulfonamidato ligand was developed. Using readily available β-amino alcs. as chiral aminating agents, a range of benzo-fused and acyclic ketones were successfully reduced with formic acid in methanol at 40°C to afford amines with favorable chemo- and diastereoselectivities. The amino alc.-derived chiral auxiliary was easily removed by mild periodic oxidants, leading to optically active primary β-arylamines without erosion of the optical purity (up to 97% ee). The excellent catalytic performance was retained even upon lowering the amount of catalyst to a substrate/catalyst (S/C) ratio of 20,000, and the amination could be performed on a large scale exceeding 100 g. The precise hydride transfer to iminium species generated from the ketonic substrate and the chiral amine counterpart was suggested by the mechanistic studies on stoichiometric reactions of isolable hydridoiridium complexes and model intermediates such as N,O-acetal, enamine, and iminium compounds

Cobalt(II) glyoxime and heterocycle complexes [Co(LL)2pyCl]n+ (LL – α-dioxime, 8-quinolinols, α-diketone dihydrazides, bipyridines, phenanthrolines, pyridyltetrazoles, etc.; n = 0-2) were generated in situ and screened for cocatalytic activity in Eosin Y-catalyzed photoreduction of water in the presence of triethylamine as sacrificial reductant. Noble-metal photosensitizers and water reduction co-catalysts (WRCs) still present the highest activity in homogeneous photocatalytic hydrogen production The search for earth-abundant alternatives is usually limited by the time required to screen new catalyst combinations; however, here, we utilize newly designed and developed high-throughput photoreactors for the parallel synthesis of novel WRCs and colorimetric screening of hydrogen evolution. This unique approach allowed rapid optimization of photocatalytic water reduction using the organic photosensitizer Eosin Y and the archetypal cobaloxime WRC [Co(GL1)2pyCl], where GL1 is dimethylglyoxime and py is pyridine. Subsequent combinatorial synthesis generated 646 unique cobalt complexes of the type [Co(LL)2pyCl], where LL is a bidentate ligand, that identified promising new WRC candidates for hydrogen production D. functional theory (DFT) calculations performed on such cobaloxime derivative complexes demonstrated that reactivity depends on hydride affinity. Alkyl-substituted glyoximes were necessary for hydrogen production and showed increased activity when paired with ligands containing strong hydrogen-bond donors. Using a newly developed method of H2 detection using colorimetric tape, we screened a massive parallel library of cobaloxime water reduction catalysts. This noble-metal-free system of photocatalytic water reduction was optimized using Eosin Y as a photosensitizer. Screening identified a series of intriguing heteroleptic species with high activity, while DFT calculations of potential reaction intermediates correlated the activity of homoleptic cobaloximes to their hydride binding affinity.

Herein, we developed an electronic effect-guided rational design strategy to enhance the enantioselectivity of Candida antarctica lipase B (CALB) mutants towards bulky pyridyl(phenyl)methanols. Compared to W104A mutant previously reported with reversed S-stereoselectivity toward sec-alcs., three mutants (W104C, W104S and W104T) displayed significant improvement of S-enantioselectivity in the kinetic resolution (KR) of various Ph pyridyl Me acetates due to the increased electronic effects between pyridyl and polar residues. The electronic effects were also observed when mutating other residues surrounding the stereospecificity pocket of CALB, such as T42A, S47A, A281S or A281C, and can be used to manipulate the stereoselectivity. A series of bulky pyridyl(phenyl) methanols, including S-(4-chlorophenyl)(pyridin-2-yl) methanol (S-CPMA), the intermediate of bepotastine, were obtained in good yields and ee values.

The instability of the perovskite solar cells (PSCs) toward UV irradiation and moisture is a limiting factor in terms of commercialization even after achieving excellent power conversion efficiencies (PCEs). Herein, an advanced triple passivation technique has been strategically designed and demonstrated utilizing UV-absorbing 2-benzoylpyridine (BP) mols. as a passivation additive to laminate perovskites and improve PSC stability. Double layers of BP were coated on both sides of the perovskite layer, and the mol. was also incorporated into the precursor solution This strategy significantly improved the perovskite crystallinity and film quality, lowered the recombination, and enhanced the carrier transport in the PSC. The triple-passivated device exhibited a high PCE of 20.46% with almost negligible hysteresis. Further, passivated large-area (2.5 cm2) devices were also fabricated that demonstrated a PCE of 18.61%. Moreover, the triple passivation approach exhibited impressive UV and ambient stability because it can effectively shield the perovskite layer from UV illumination and moisture.
