Nano-Structured Metal Chalcogenides as Reagents for the Catalytic Carbon-Sulfur Bond Formation in Cross-Coupling Reaction

摘要

A new approach for the catalytic carbon-sulfur bond formation via cross-coupling reaction is reported. For the first time nano-structured nickel organosumdes [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.
