چکیده مقاله :
Mesoporous materials are porous materials with periodically ordered pore in the range of 2 ~ 50 nm. They have large accessible surface areas and tunable pore sizes, which are of particular benefit for mass transport and dispersion of electrons / reactants [1]. Mesoporous silica materials like MCM‐41 has attracted much attention because of their different usages, and have versatile applications in materials science and several unique properties including good thermal stability, large surface area, unique channel structure, large pore volume, good biocompatibility and also easy surface functionalization [2]. Herein, we decided to introduce new nanocatalyst MCM-41@SnPr-Kryf.23-Mn catalyzed the oxidation of primary and secondary alcohols to corresponding oxidized carbonylated compounds in the presence of hydrogen peroxide in acetonitrile and acetic acid in high yield under mild condition (Scheme 1). Scheme1: Oxidation of primary and secondary alcohols (1) to corresponding carbonylated compounds (2 and/or 3) with catalytic amount of MCM-41@SnPr-Kryf.23-Mn nanocatalyst.
