Synthesis of Schiff bases of 2-amino benzo[d]thiazole from higher hetero aldehydes and ketones using Mo-Al2O3 composite-based organocatalyst

Abstract

A new metal supported organo catalyst has been successfully employed to carry out the high yield Schiff’s base reaction at ambient temperature. This methodology has the benefits of straightforward conditions, excellent yields, no work-up, environmental benign process and reusable solid catalyst. The catalyst speeds up the Schiff base reaction with less time and several Schiff bases have been synthesized and characterized with IR, 1H and 13C NMR techniques.
