已经研究了从氢硅烷选择性合成氟硅烷、氟氢硅烷和氯氟硅烷的方法。 Me(2)PhSiH和MePh(2)SiH与由2当量CuCl2、1当量KF和催化量的CuI组成的混合物在THF中在室温下反应，分别以高产率得到Me(2)PhSiF和MePh(2)SiF。通过对该反应的轻微修改，n-Hex(2)SiHF、Ph(2)SiHF、MeMesSiHF、MePhSiHF、PhSiH(2)F 和 PhSiHF(2) 可以很容易地由相应的聚氢硅烷选择性地以高产率制备。在催化量的 CuI 存在下，用 2 当量的 CuCl2 处理 MePhSiHF 和 Ph(2)SiHF，得到相应的氯氟硅烷 MePhSiClF 和 Ph(2)SiClF。
A selective synthesis of fluoro-, fluorohydro-, and chlorofluorosilanes from hydrosilanes has been examined. The reaction of Me(2)PhSiH and MePh(2)SiH with a mixture consisting of 2 equiv of CuCl2, 1 equiv of KF, and a catalytic amount of CuI in THF at room temperature afforded Me(2)PhSiF and MePh(2)SiF in high yields, respectively. With slight modification of this reaction, n-Hex(2)SiHF, Ph(2)SiHF, MeMesSiHF, MePhSiHF, PhSiH(2)F, and PhSiHF(2) could be readily prepared from the corresponding polyhydrosilanes selectively in high yields. Treatment of MePhSiHF and Ph(2)SiHF with 2 equiv of CuCl2 in the presence of a catalytic amount of CuI afforded the respective chlorofluorosilanes, MePhSiClF and Ph(2)SiClF.
