Abstract: Abstract Four compounds derived from 2-hydroxy and 2-mercaptobenzimidazole were synthesized and characterized by FT-IR spectroscopy, nuclear magnetic resonance and elemental analysis. Two of the resulting compounds –diethyl 2-oxo-1H benzo[d]imidazole-1,3(2H)-dicarboxylate and diethyl 2-thioxo-1H benzo[d]imidazole-1,3(2H)-dicarboxylate– were crystallized… read more here.
