In the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(0), chlorodisilanes of type MenSi2Cl6−n (n = 2–5) add to acetylene to afford 1,2-bis(chlorosilyl)ethenes in reasonable yields.
在催化量的四(三苯基膦)钯(0)存在下,将Me n Si 2 Cl 6– n(n = 2–5)型的氯乙硅烷加到乙炔中,制得1,2-双(氯甲硅烷基)乙烯合理的产量。
UNUSUAL REGIOSELECTIVE HYDROSILYLATION OF ETHYNYLMETHYLDICHLOROSILANE WITH DIMETHYLCHLOROSILANE CATALYZED BY TETRAKIS(TRIPHENYLPHOSPHINE)PLATINUM(0)
The hydrosilylation of ethynylmethyldichlorosilane with dimethylchlorosilane catalyzed by tetrakis(triphenylphosphine)platinum(0) was found to show quite an unusual regioselectivity to afford the geminal product, 1-(methyldichlorosilyl)-1-(dimethylchlorosilyl)ethene, almost exclusively.
