The Pd-catalyzed cross-coupling of cyclic thioamides and thioureas with alkenylboronic acids, vinyl- and (het)arylstannanes, and arylsiloxanes in the presence of stoichiometric amounts of a Cu(I) cofactor is described. The desulfitative C−C cross-coupling protocol of the Liebeskind−Srogl type is performed under neutral conditions and can be applied to a range of heterocyclic structures with embedded
