The synthesis of two benzonaphthothiophenes and of four benzophenanthrothiophenes through Elbs cyclodehydration of ortho-methylated aroylbenzo[b]thiophenes is described. The occurrence of a rearrangement of the thiophene ring in the course of the cyclization is discussed as well as the influence of the temperature on a concurrent cyclodehydration process. Several of these poly-condensed thiophenes were found to be carcinogenic in mice.
