A. Thirupathaiah^1* and D. Dasharatham²

Abstract:

A simple and efficient method has been developed for the synthesis of some novel Schiff bases via the reaction of aromatic aldehydes with 2-aminobenzimidazole by using catalytic amount of BiCl3 in an organic solvent under microwave irradiation. Some advantages of this protocol are its very good yields, use of available catalysts, simple workup procedure, and short reaction times.

Keywords:
