摘要：

The aminofluorosilane [(CMe3)2MeSiNH]2SiF2 (1) is formed by treatment of SiF4 with (CMe3)2MeSiNHLi. The mono-(2) and dilithium (3) derivatives of 1 are obtained by treatment with Me3CLi. Treatment of 1 with four equivalents Me3CLi and THF gives the lithium(lithiosilyldiamide) 4, a salt with a cyclic (LiN2Si)- anion. The lithium(lithiosilyldiamide) 5 is formed when the donor [12]crown-4 is used for coordination of the Lewis acid lithium. The crystal structure for 5 has been determined.
