A new approach for the catalytic carbon-sulfur bond formation via cross-coupling reaction is reported. For the first time nano-structured nickel organosulfides [Ni(SAr)(2)] (n) were used as a source of SAr groups in catalytic cross-coupling reaction. A unique effect of morphology control of the reactivity of SAr groups in cross-coupling reaction was found. Synthesized nano-structured particles were characterized by field-emission scanning electron microscopy and their reactivity was studied by NMR in solution. Cross-coupling reaction with Cu catalyst was shown to proceed in the liquid phase and involve leaching, whereas the reaction with Pd catalyst is more complex and may involve both-homogeneous and heterogeneous pathways.
