Microwave-assisted synthesis of 2,4,5-triaryl-imidazole; a novel thermally induced N-hydroxyimidazole N-O bond cleavage.

Richard B Sparks1, Andrew P Combs.   

Abstract

[reaction: see text] 2,4,5-Triaryl-imidazoles were synthesized directly from the keto-oxime in moderate to good yields via cyclization to the N-hydroxyimidazole and an unprecedented in situ thermal reduction of the N-O bond upon microwave irradiation at 200 degrees C for 20 min.
