Ni-catalyzed cross-couplingreactions have become a very attractive tool for the stereoselective construction of valuable organic chiral materials. While various nucleophiles are used in such transformation, organotitanium (IV) has not been used before. Herein we demonstrate, for the first time, that organotitanium species can serve as efficient coupling partners in asymmetric cross-couplings, which have

A highly efficient and simple cross-coupling reactions of aryltitanium reagents with -aryl thiosuccinimides for the synthesis of arylsulfide derivatives using Cu(acac) (20 mol%) as catalyst are reported. Under the optimum reaction conditions, the coupling reaction between (hetero)aryltitanium reagents with -aryl thiosuccinimides can be carried out smoothly, 18–93 % isolated yields of arylsulfides were
