Abstract
Indolo[6,5-d]benzo[b]thiophene, indolo[4,5-d]benzo[b]thiophene, indolo[5,6-d]benzo-[b]thiophene, and indolo[5,4-d]benzo[b]thiophene were obtained from the 2- and 3-dibenzothienylhydrazones by means of the Fischer reaction. The structures of the compounds obtained were proved by their PMR, IR, UV, and mass spectra.
