Title
Thiol-yne click on nano-starch: An expedient approach for grafting of oxo-vanadium Schiff base catalyst and its use in the oxidation of alcohols
Abstract

•Grafting of oxo-vanadium complex on nanocrystalline starch by click method.•Novel metal free approach for the heterogenization of homogeneous catalyst.•Utilization of renewable resources as catalyst support.•Development of enviro-economic methodology for oxidation of alcohols.•First successful application of Thiol-yne coupling in the area of catalysis.

The metal-free stoichiometric click reaction between thiol-functionalized nanocrystalline starch and yne-functional oxo-vanadium Schiff base has been demonstrated to be a simple, quantitative, mild and efficient approach for the development of heterogenized homogeneous complex via covalent bonding. The developed catalyst has found to be highly efficient and recyclable for the oxidation of various alcohols to corresponding carbonyl compounds with t-BuOOH under mild reaction conditions. Importantly, no leaching of metal or ligand is observed during the course of the reaction.
