title: Rhodium Thiavinyl Carbenes from 1,2,3-Thiadiazoles Enable Modular Synthesis of Multisubstituted Thiophenes.
abstract: The rhodium-catalyzed transannulation reaction between 1,2,3-thiadiazoles and alkynes, proceeding via intermediacy of the previously unknown Rh thiavinyl carbene, toward a highly efficient and regioselective synthesis of up to fully substituted thiophenes is described.
