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.
