Aqueous aerobic oxidation of alkyl arenes and alcohols catalyzed by copper(ii) phthalocyanine supported on three-dimensional nitrogen-doped graphene at room temperature

Abstract

Copper(ii) tetrasulfophthalocyanine supported on three-dimensional nitrogen-doped graphene-based frameworks was synthesized and introduced as a bifunctional catalyst for selective aerobic oxidation of alkyl arenes and alcohols to the corresponding carbonyl compounds. The ease of catalyst separation, high turnover, low catalyst loading and recyclability could potentially render it applicable in industrial setting.

A Transition-Metal-Free Homogeneous TEMPO-Based Catalyst: Aerobic Oxidation of Alcohols in Aqueous Media

“…Recently, their use has increased. [16,17] In continuation of our efforts to introduce new and highly efficient strategies for various organic transformations, [18][19][20][21] we wish to report herein a homogeneous transition-metal-free catalyst, TEMPO/NaNO 2 /NH 4 Br/TMG-SO 3 H, for the aerobic oxidation of a wide range of alcohols to the corresponding carbonyl compounds.…”

Design, preparation and characterization of Cu/GA/Fe3O4@SiO2 nanoparticles as a catalyst for the synthesis of benzodiazepines and imidazoles

“…In continuation of our work towards the synthesis of benzodiazepine and imidazole derivatives as well as our interest in the preparation and use of heterogeneous catalysts in organic synthesis, we synthesized and characterized magnetically recoverable nanocomposite particles (NCPs), Cu/GA/Fe 3 O 4 @SiO 2 , and investigated their activity as nanocatalyst in the synthesis of substituted benzodiazepines and 2,4,5‐trisubstituted imidazoles. The corresponding reactions are shown in Scheme .…”
