A facile and selective palladium-catalyzeddomino procedure has been developed for the preparation of 2-carbonylbenzo[b]thiophene derivatives from 2-gem-dihalovinylthiophenols. This protocol involves intramolecular C–S coupling/intermolecular carbonylation cascade sequences and allows access to various highly functionalized benzo[b]thiophenes in moderate yields.
