An Unexpected Synthesis of 2H-Benzimidazole Derivatives

Abstract:

Treatment of 1,2-phenylenediamines and 3-(N-phenyl-N-methyl) aminoacrolein with ZrCl₄ as catalyst in refluxing 95% ethanol afforded unexpected 2H-benzimidazole derivatives as the major products. It was determined that the formation of 2H-benzimidazoles was not from the decomposition of the 2-aminovinyl benzimidazoles.
