The effect of the structure of the fluoroalkyl group RFC2H4, where RF = CF3, C6F13 and (CF3)2CF, on the synthesis and reactivity of organolithium reagents RFC2H4Li towards trimethylchlorosilane, (CH3)3SiCl, and tris(fluoroalkyl)silanes R1R2R3SiF where R = RFC2H4, 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)2CFC2H4>2SiF(C2H4C6F13), and fluorinated tetraalkylsilanes such as C6F13C2H4Si(CH3)3 and <(CF3)2CFC2H4>2Si(C2H4C6F13)(C2H4CF3).All the products have been characterized by 1H, 19F and 29Si NMR spectroscopy. - Keywords: Synthesis; Reactivity; Alkylation; Fluorinated organolithium reagents; NMR spectroscopy
