Abstract
Isomeric 2-formylbenzo[b]thiophene-3-selenol and 3-formylbenzo[b]thiophene-2-selenol and their sulfur analogs were obtained by nucleophilic substitution of the bromine atom in 3-bromo-2-formylbenzo[b]thiophene or the isomeric 2-bromo-3-formylbenzo[b]thiophene by a hydroselenide or hydrosulfide group by the action of an alcohol solution of NaSeH or NaSH, as well as by the action of selenourea with subsequent alkaline hydrolysis. Various Schiff bases were obtained from the isolated formyl-substituted selenols and thiols by two methods, and complexes with divalent Zn, Cd, and Ni were obtained by reaction of the Schiff bases with the corresponding metal acetates.
