We have demonstrated that indium tri(organothiolate) are effective nucleophilic coupling partners in Pd-catalyzed C-S cross-coupling reactions with high atom efficiency and complete regio- and chemoselectivity. With these results, we examined the sequential selective C-S cross-coupling reactions and In-mediated allylation and allenylation reactions in one-pot. Using halobenzaldehydes and α-halo-α,β-enals, aryl-alkyl, aryl-vinyl, and aryl-aryl sulfides having homoallyl- and allenyl alcohols were produced in good to excellent yields. Furthermore, we applied the present method to multicomponent reactions composed of selective double C-S bond formation through cross-coupling reactions followed by addition of allylindium to aldehyde gave bis(sulfides) having considerable complexity in one-pot.
