Abstract A catalyst‐free photochemical N‐acylation of azoles with aldehydes has been developed using inexpensive BrCCl 3 as the oxidant. This transition‐metal‐ and photocatalyst‐free amidation proceeded efficiently a wide variety substrates to give corresponding N‐acylazoles, including for late modification pharmaceutically active molecules, on gram‐scale.

Reported herein is a photoredox/cobaloxime dual-catalytic approach to execute tandem dehydrogenative azolation and aromatization of tetrahydronaphthalene for rapid construction N-(β-naphthyl)azole architectures. This protocol highlights noble metal-free external oxidants-free conditions, step- atom-economy, site-selectivity. A preliminary mechanistic study has uncovered that the transformation undergoes N-centered radical mediated C–H/N–H cross-coupling followed by saturated naphthyl surrogates under visible light irradiation, DFT calculations elucidate

Abstract Developing highly active electrocatalysts for the benzylamine oxidation reaction (BOR) is very imperative organic compounds upgrading. Meanwhile, clarifying underlying BOR mechanism of remarkable significance but still confronts challenges. Herein, bimetallic nickel‐cobalt hydrogen phosphate nanowires (NiCo‐HPNWs) are put forward as a high‐performance anodic catalyst selective BOR. Furthermore, NiCo‐HPNWs used proof‐of‐concept model to understand synergistic effects between Ni and Co atoms during process. It found that shows excellent electrocatalytic performance, with small onset potential 0.265 V versus. Ag/AgCl high faradic efficiency (FE) 93.0% benzonitrile (BN) production at 0.40 Ag/AgCl. Also, FEs BN can reach ≈80% voltages from 1.50 1.65 by coupling evolution in two‐electrode electrolyzer. Potential‐dependent situ Raman spectroscopy sheds light on direct electro‐oxidation (BA) over catalyst. In combination X‐ray photoelectron density functional theory calculations, charge transfer behavior revealed, which endows favorable distribution promote BA adsorption desorption surface, thereby leading expedited kinetics enhanced electrochemical activity.
