The nitration of dithienopyridine (2) and dithienopyridine (3) has been studied.Nitration of 2 occurred in both positions of the c-fused thiophene ring, while 3 was predominantly substituted in the 2-position.The structures of the nitro derivatives were proven by extensive use of 1H and 13C nmr spectroscopy.
