摘要：

A new protocol for the synthesis of [1, 2-a]-fused benzimidazoles and imidazoles has been developed using intramolecular homolytic aromatic substitution via omega-alkyl radicals generated from 1-(omega-benzeneselenylalkyl)- 2-(benzenesulfenyl)-benzimidazoles and -2-(p-toluenesulfonyl)imidozoles.
