The effect of the pore size of nanoporous gold on electrochemical reduction of functionalized carbonyl compounds was investigated. NPG with a pore size of similar to 30 nm significantly enhanced the reactivity with high chemo-selectivity at a low-potential. Typically, p-nitrobenzaldehyde reduction demonstrates a high turnover frequency (TOF) up to 232 000 h(-1).

Substituted arylethylamines represent a key structural motif in natural, pharmaceutical, and agrochemical compounds. Access to such scaffolds has been the subject of long-standing synthetic interest. Herein, we report the synthesis of such scaffolds via a palladium-catalyzed C(sp(3))-C(sp(3)) coupling between (chloromethyl)aryls and air-/moisture-stable N,N-dialkylaminomethyltrifluoroborate salts. Rapid hit identification was achieved using microscale high-throughput experimentation and was followed by millimolar-scale reaction parameter optimization. A range of structurally and electronically varied arylethylamine products were obtained in moderate to excellent yields (27-96%, >60 examples). The reaction mechanism is proposed to proceed via formation of a trialkylbenzylammonium species prior to oxidative addition.

A novel nonanuclear copper(II) complex obtained by a facile one-pot self-assembly was found to catalyze the hydroboration of ketones and aldehydes with the absence of an activator under mild, solvent-free conditions. The catalyst is air-and moisture-stable, displaying high efficiency (1980 h(-1) turnover frequency, TOF) and chemo-selectivity on aldehydes over ketones and ketones over imines. This represents a rare example of divalent copper catalyst for the hydroboration of carbonyls.

An in situ developed Lewis acid-surfactant-SiO2-combined (LASSC) nanocatalyst was used, for the first time, as a green and effective promoting medium for the electrophilic activation of aldehydes under solvent-free and dry grinding conditions. The advantages of using the LASSC nanocatalyst include avoiding the generation of wastewater containing sodium dodecyl sulfate and the use of toxic reagents, excellent reusability of the catalyst, and obtaining a high yield of bis(indolyl)methanes.

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.

A practical method for the oxidation of aromatic side chains was established for the preparation of aromatic aldehydes and ketones. Using NiCl2 as the catalyst, substituted toluenes were oxidized with Na2S2O8 at the benzvlic site for the synthesis of the corresponding aldehydes in the yield of 22%similar to 79%. Ethylbenzene analogs were oxidized more easily to obtain the corresponding ketones with 64%similar to 84% yields. The oxidation of benzyl alcohol analogs was completed to acquire the corresponding carbonyl compounds in shorter time with better selectivity and yields. The method has the advantages such as the mild reaction conditions, no requirement for precious metals or additional promoter, and good selectivity.

A convenient one-pot synthesis of allylsilanes from enolizable methyl aryl ketones has been developed. The first step involves nucleophilic addition of the trimethylsilylmethyl group to ketones using the alkylation method developed by Ishihara with slight modification to generate the corresponding beta-silylalkoxides. The second step entails addition of diisobutylaluminum chloride and heating at about 130 degrees C overnight to afford allylsilanes in fair yields.

The first highly efficient and practical chiral BrOnsted acid catalyzed dynamic kinetic asymmetric hydroamination (DyKAH) of racemic allenes and asymmetric hydroamination of unactivated dienes with both high E/Z selectivity and enantioselectivity are described herein. The transformation proceeds through a new catalytic asymmetric model involving a highly reactive pi-allylic carbocationic intermediate, generated from racemic allenes or dienes through a proton transfer mediated by an activating/directing thiourea group. This method affords expedient access to structurally diverse enantioenriched, potentially bioactive alkenyl-containing aza-heterocycles and bicyclic aza-heterocycles.

A supported ruthenium (Ru) nanoparticle on amino-functionalized Fe3O4 (Fe3O4/NH2/Ru) was successfully prepared by a novel and simple one-pot template-free method combined with a metal adsorption-reduction procedure. The characterization results show that the introduced amino group (1,6-hexanediamine) can effectively stabilize the Ru nanoparticles and allow the particles to maintain a narrow size distribution, monodispersity and a regular morphology. Fe3O4/NH2/Ru exhibits excellent catalytic activity for the transfer hydrogenation of nitro compounds by the use of NaBH4 as the hydrogen donor. The higher activity of this catalyst was attributed to the higher dispersion and smaller particle size of Ru nanoparticles, as observed from the characterization results. Moreover, the catalyst can be easily recovered by an external magnetic field, recycled five times and reused without any loss of activity.

Novel arginine-functionalized starch-based nanoparticles (Arg-SNPs) were synthesized and characterized by Fourier transforms infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX), X-ray diffraction (XRD) and thermos-gravimetric analyses (TGA) techniques. Arg-SNP was used as a highly efficient and macromolecule-supported recyclable nanocatalyst for the one-pot reaction between thiourea and iodine with various substituted methylcarbonyls to afford the corresponding diheteroaryl thioethers in high-to-quantitative yields. The nanocatalyst was recycled at least five times without significant decrease in the catalytic activity. (C) 2019 Elsevier B.V. All rights reserved.
