Abstract

We consider a radical-ion mechanism for dehydroaromatization of benzimidazolines by triarylmethyl cations, including as the initial step electron transfer from the hydroheteroaromatic compound to the electrophilic reagent. We draw the conclusion that there is significant weakening of the C(2)-H bond in the benzimidazoline radical cation formed in this stage.
