Abstract
Di-tert-butylfluorosilyl-tert-butylphosphane (1) reacts with n-C4H9Li to give the lithium salt (CMe3)2SiF-PLi(THF)3CMe3 (2) and butane. The crystal structure of 2 has been determined. Fluorosilylphosphanes of the type (CMe3)2SiFP(R)CMe3 [R = SiMe3 (5), SiCl2Me (6). SiCl3 (7), SiF2C6H5 (8), BFN (SiMe3)2 (9), SiClMeP(CMe3)SiF(CMe3)2 (10)] are obtained in the reaction of 2 with halogenosilanes and -borane. 6 and 7 undergo rearrangement via chloro-fluoro exchange reaction to give (CMe3)2SiCl-P(SiClRF)CMe3 [R = Cl (11), Me (12)].Keywords
