摘要：

The effect of the structure of the fluoroalkyl group R(F)C(2)H(4), where R(F)=CF3, C6F13 and (CF3)(2)CF, on the synthesis and reactivity of organolithium reagents R(F)C(2)H(4)Li towards trimethylchlorosilane, (CH3)(3)SiCl, and tris(fluoroalkyl)silanes, R(1)R(2)R(3)SiF, where R=R(F)C(2)H(4), has been studied. As a result, new fluorinated organolithium reagents have been synthesized, as well as new silanes such as a tris(fluoroalkyl)fluorosilane, [(CF3)(2)CFC2H4]2SiF(C2H4C6F13), and fluorinated tetraalkylsilanes such as C6F13C2H4Si(CH3)(3) and [(CF3)(2)CFC2H4]Si-2(C2H4C6F(13))(C2H4CF3). All the products have been characterized by H-1, F-19 and Si-29 NMR spectroscopy.
