Abstract: | We have established that 2,4-dimethylbenzob]furo3,2-c]pyrylium and 2,4-dimethylbenzob]thieno3,2-c]pyrylium salts can undergo recyclization to 3-dialkylamino derivatives of dibenzofuran and dibenzothiophene when treated
with secondary amines. We compare the physicochemical and spectral characteristics of the compounds obtained with the recyclization
products of 1,3-dimethylbenzob]furo2,3-c]- and 1,3-dimethylbenzob]thieno2,3-c]pyrylium salts.
