CuWO₄ as a photocatalyst for room temperature aerobic benzylamine oxidation

Abstract

The aerobic photochemical oxidation of benzylamine was carried out on the ternary oxides CuWO and BiVO as a test proton-coupled-electron-transfer reaction in acetonitrile. Both oxides give the coupled imine product, N-benzylidenebenzylamine, in near quantitative (98-99%) yield, with rate constants of 0.34 h g and 0.70 h g for CuWO and BiVO, respectively.

Understanding and Improving Photocatalytic Activity of Pd-Loaded BiVO4 Microspheres: Application to Visible Light-Induced Suzuki–Miyaura Coupling Reaction

“…To evaluate the photocatalytic activity of Pd–BiVO 4 (HT), a representative BiVO 4 catalyst was prepared by a reported solid-state synthesis method; the sample is denoted as BiVO 4 (SS). , The Pd-loaded BiVO 4 composite was also prepared by photodeposition of Pd nanoparticles on BiVO 4 [Pd–BiVO 4 (SS)] (Figure S7).…”

Synthesis, Characterization, and Photocatalytic Application of Type‐II CdS/Bi2W2O9 Heterojunction Nanomaterials towards Aerobic Oxidation of Amines to Imines

“…The adverse environmental impact of oxidants, solvent wastage, and unwanted by‐product formation is a concern in the conventional amine‐oxidation processes , . To date, very few photocatalysts, such as TiO 2 , Nb 2 O 5 , WS 2 , BiVO 4 , BiOX, g‐C 3 N 4 , AgI/AgVO 3 , Au‐clusters, ZnIn 2 S 4 , CuWO 4 , and organic polymers, have been studied for the oxidation of amines . Some of these reported photocatalytic protocols require longer times, employ photocatalysts with poor response to visible light, and require molecular O 2 to carry out the oxidation reaction.…”

Visible Light Driven Oxidative Coupling of Amines and P(O)−H/P−OR Compounds under Photocatalyst‐Free Conditions

“…(Table 2, 3 m – 3 y ). Benzylic amines could couple with 1 a (Table 2, 3 q and 3 r ), despite their propensity to form imines under peroxides oxidation [19] . Again, tert‐butylamine is an inert amine candidate here ( 3 t ).…”

“…Benzylic amines could couple with 1 a (Table 2, 3 q and 3 r), despite their propensity to form imines under peroxides oxidation. [19] Again, tert-butylamine is an inert amine candidate here (3 t). In addition, the oxidant-sensitive anilines were viable substrates whereas a slightly poorer yields of phosphinic amides (3 u-3 y) were obtained than that of simple alkylamines (cf.…”
