Synthesis of cupric acetate selective receptor derived from alanyl glycoconjugate and their application in selective oxidation of benzylic alcohols

Abstract

Cupric acetate sensing ability of alanyl-(4,6-O-ethylidene-β-D-glucopyranosylamine) derived receptor (L-N2O2) has been explored using fluorescence and UV–visible absorption spectroscopy. Cupric acetate quenches the fluorescence intensity of L-N2O2 with a correlation coefficient, R = 0.978 and Stern Volmer constant, KSV = 38,067 M− 1 revealing the possibilities of interaction via dynamic mode. Further, copper complex of L-N2O2 has been utilized in selective oxidation of primary and secondary alcohols into the corresponding carbonyl compounds.
