Palladium-Catalyzed Carbon−Sulfur Cross-Coupling Reactions with Indium Tri(organothiolate) and Its Application to Sequential One-Pot Processes

It was found that indium tri(organothiolate) is an effective nucleophilic coupling partner in Pd-catalyzed C-S cross-coupling reactions to produce the functionalized sulfides in excellent yields with high atom efficiency and complete regio- and chemoselectivity. The present method was efficiently applied to the sequential one-pot processes composed of selective double C-S cross-coupling reactions and addition of allylindium or allenylindium to aldedyde to give the functionalized sulfides and bis(sulfides).
