Palladium-catalyzed domino C-S coupling/carbonylation reactions: An efficient synthesis of 2-carbonylbenzo[ b ]thiophene derivatives
A facile and selective palladium-catalyzed domino 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 carbonylatio
