    Regioselective hydrosilylation of terminal acetylenes via acetylene–Co2(CO)4dppm complex: effects of the ligands in acetylenedicobalt complex
    摘要:
    The regioselective hydrosilylation of the acetylenedicobalt complex on the terminal acetylene with special reference to the ligands to produce a vinylsilane is described. It was found that the use of the ligands exchanged dicobalttetracarbonyl bis(diphenyl-phosphino)methane complex dramatically changed the regioselectivity compared to the corresponding dicobalthexacarbonyl complex.
