Abstract

Abstract: Herein, we report on the facile synthesis of a heterogeneous copper nanocatalyst and its combination with 2, 2, 6, 6‐tetramethyl‐1‐piperidinyloxy (TEMPO) for the aerobic oxidation of alcohols to their corresponding carbonyl compounds. This low cost copper nanocatalyst was found to exhibit excellent recyclability, making it a highly attractive catalytic system from an economical and environmental point of view. Extensive characterization of the catalyst by a number of techniques revealed that it was comprised of well‐dispersed Cu(I/II) nanoparticles with an average size of around 6 nm. Abstract : Copperative Catalysis : The synthesis and characterization of a heterogeneous catalyst based on Cu(I/II) nanoparticles immobilized on amino‐functionalized controlled pore glass has been described. This recyclable Cu nanocatalyst was found to efficiently mediate the aerobic oxidation of both primary and secondary alcohols to their corresponding carbonyl compounds, when used together with TEMPO.
