The reaction of methylchlorodisilanes with gem-polyhalides in the presence of organic bases has been investigated.The compounds CXCl2SiMeCl2 (X = Cl, H, F and SiMeCl2) were obtained in moderate to high yields from Cl2MeSiSiMeCl2 and polyhalomethanes (e.g., CCl4, CHCl3, CFCl3 and CCl3SiMeCl2) with PPh3 or Bu4NCl as catalyst.The reaction of 1,1,2-trichlorotrimethyldisilane with CCl4 afforded a 1:1 mixture of CCl3SiMeCl2 and CCl3SiMe2Cl.Also, XC6H4CCl2SiMeCl2 (X = H and 4-Cl) were obtained in moderate yields from Cl2MeSiSiMeCl2 and XC6H4CCl3 with Bu4NCl or Bu4NF as catalyst.
