Title
Saccharide derived dinuclear Cu(II) complex: An efficient catalyst for oxidation of catechol and benzylic alcohols
Abstract

Catalytical aspect of 4,6-O-ethylidene-β-D-glucopyranosylamine derived dinuclear Cu(II) complex has been explored. The complex exhibits good catecholase like activity and oxidizes model substrate 3,5-di-tert-butylcatechol to 3,5-di-tert-butyl-o-quinone. The complex also acts as selective catalyst to oxidize the primary and secondary alcohols to corresponding carbonyl compounds in excellent yield (65–82%) under mild conditions.

Graphical abstractGlycosylamine derived dinuclear Cu(II) complex acts as hetereogeneous catalyst to oxidize alcohols into corresponding carbonyl compounds in ionic liquid, [bmim][BF4]. It also oxidizes 3,5-di-tert-butylcatechol to 3,5-di-tert-butyl-o-quinone in a mixed solvent (DMSO-MeOH) at room temperature.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► Catalytic activities of sugar derived dinuclear Cu(II) complex has been explored. ► The complex exhibits a good amount of catecholase like activity. ► It also selectively oxidizes primary and secondary alcohols to carbonyl compounds. ► The protocol for alcohol oxidation is eco-friendly and the catalyst is recyclable.
