摘要：

The P-methyl (silylamino)phosphines Me3Si(R)NPMe2 (1, R=Me3Si; 2, R=t-Bu; 3, R=Me), (Me3Si)2NP(Ph)Me (4), t-BuMe2Si(R)NPMe2 (5, R=Me3Si; 6, R=Me), and Me2PMe2 (7) are conveniently prepared by treatment of lithium silylamides with PCl3 or PhPCl2 followed by MeMgBr. Phosphines 1-7 react with MeI to form the (silylamino)phosphonium iodides which, when allowed to react with n-BuLi, usually undergo dehydrohalogenation and N→C silyl migration to afford the (silylmethyl)phosphinimines Me3SiN⎓P(CH2SiMe3)RR' (8, R=R'=Me; 9, R=Me, R'=Ph; 10, R=R'=Ph), Me2 (11), RMe2SiN⎓P(CH2SiMe2R')Me2 (12a, R=Me, R'=t-Bu; 12b, R=t-Bu, R'=Me), and t-BuN⎓P(CH2SiMe3)Me2 (13). © 1979, American Chemical Society.
