Abstract
Phosphaethenes of the type (Me3Si)2C = P -NRSiMe3 R = C10H15 (7), CMe3 (8), 2.4.6-Me3C6H2 (10)), LiF, and Me3SiF are obtained in the reaction of the aminodifluorophosphanes (3-5) with the lithium salt of tris(trimethylsilyl)methane (1). 10 is isolated as by-product. The main product is F2PC(SiMe3)3 (9). The lithium salt of tris(trimethylsilyl)silan (2) reacts with 3 -6 to give the thermally stable substitution compounds (Me3Si)3Si -PF-NRSiMe3 (11-14). The fluorosilylphosphane Me3Si(CMe3)P -SiFMe - N(SiMe3)2 (15) is formed in the reaction of Me3Si(CMe3)PLi and F2SiMeN (SiMe3)2.Keywords
