2-[2-(1-benzoyl-4-methyldibenzo- thienyl-2)benzo[b]thienyl-3]phenyl- 1-ethanone – a new product of the reaction of 1-methyl-3-phenylbenzo- thieno[2,3-c]pyrilium perchlorate with nucleophilic reagents
On the interaction of 1-methyl-3-phenylbenzothieno[2,3-c]pyrilium perchlorate with primary and secondary amines and alkalis in aqueous media a product of cyclocondensation of 2-acetyl-3-phenacyl-benzo[b]thiophene – 2-[2-(1-benzoyl-4-methyldibenzothienyl-2)benzo[b]thienyl-3]phenyl-1-ethanone – was isolated in addition to the classical objects of recyclization.
