Water-mediated synthesis of 2-substituted benzimidazoles by boric acid and glycerol
Mukhopadhyay, Chhanda,Tapaswi, Pradip Kumar,Butcher, Ray J.
experimental part, p. 140 - 144 (2009/08/15)
A very simple, mild, and highly efficient green catalyst has been developed for the synthesis of 2-substituted benzimidazoles by treatment of substituted ortho-phenylenediamines and aldehydes in water at 80C in the presence of boric acid (5 mol-%) and glycerol (0.05 mL). This methodology has been standardized on 55 substrates, and nine new compounds have been synthesized.
