The transition-metal-catalyzed carbon-sulfur cross-coupling reaction is one of the fundamental processes in organic synthesis because the sulfide functional group is widely used in pharmaceuticals, functional materials, and synthesis of natural products. Sarandeses et al. developed an atom-efficient Pd-catalyzed cross-coupling reaction with triorganoindiums (R3In). We have developed an efficient Pd-catalyzed multifold (2-, 3-, and 4-fold) carbon-sulfur cross-coupling reaction of indium tri-(organothiolates) with polybromonated aromatic and heteroaromatic compounds in a one-pot procedure, producing di-, tri-, and tetrasulfides. These results indicate that indium tri(organothiolates) transfer all of three alkyl- or arylthio groups attached to indium metal to electrophilic coupling partners. These novel features, which is carried out with only a small excess of organometallic reagent and a low catalyst loading,make indiumtri(organothiolates) highly useful alternatives to other organo-metallic reagents used in transition-metal-catalyzed multifold carbon-sulfur crosscoupling reactions and also mark them out as promising reagents for organic synthesis.
