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

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.

Glycosylamine 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 as PowerPoint slideHighlights
