Abstract
Abstract o-Fuchsones formed by dehydrohalogenation of o-hydroxyaryl (diaryl) methyl chlorides with tertiary amines undergo a cyclization to eight-membered dimers of the type head to tail. The dimerization reaction is catalyzed by tertiary amines hydrochlorides involving very likely triarylmethyl cation as intermediates.
