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

Abstract

We have used a new metal supported organo catalyst successfully 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 were synthesised and given IR,¹H,¹³C NMR characterisation.
