The reaction of naphthothiophene with an aromatic hydrocarbon in the presence of aluminum chloride at 20 deg C gave either a 3-aryl-2,3-dihydronaphthothiophene by addition to the 2,3-bond or 2,3-dihydronaphthothiophene as a result of hydride abstraction.Occasionally 2-aryl-2,3-dihydronaphthothiophenes were obtained.At higher temperatures 2-arylnaphthothiophenes and 2,3-dihydronaphthothiophene were isolated.Attempts are made to rationalize the formation of these products in terms of protonation of naphthothiophene by moist aluminum chloride and reaction of the resulting electrophile with an aromatic substrate.
