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。

the hydroperoxide groups of oneperoxidemolecule. The cyclization is regioselective. The possible 12-membered bicyclicperoxide products are not produced. Unexpectedly, the peroxides are extremely explosive. The reactions of 1,2-bis[dichloro(alkyl)silyl]ethanes with 1,1-dihydroperoxy-tert-butylcyclohexane give only bicyclicperoxides containing two six-membered rings also through the replacement of
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.
