摘要：

The reactions of phosphorus halides with lithium t-butyldimethylsilyl(methyl)-amide were used to prepare the new SiNP derivatives t-BuMe2SiN(Me)X (I, X PF4; II, X PF2; III, X PCl2). The dichlorophosphine (III) is readily oxidized by Me2SO to the phosphoryl compound t-BuMe2SiN(Me)P(O)Cl2 (IV) whereas the difluorophosphine (II) does not react with Me2SO. Treatment of t-BuMe2SiN(SiMe3)Li with PCl5 gave the trichlorophosphinimime t-BuMe2SiNPCl3 (V). Steric crowding at silicon enhances the thermal stability of these compounds relative to their Me3Si analogues. © 1979.
