Abstract The aminofluorosilane [(CMe 3) 2 MeSiNH] 2 SiF 2 (1 is formed by treatment of SiF 4 with (CMe 3) 2 MeSiNHLi. The mono-(2) and dilithium (3) derivatives of 1 are obtained by treatment with Me 3 CLi. Treatment of 1 with four equivalents Me 3 CLi and THF gives the lithium (lithiosilyldiamide) 4, a salt with a cyclic (LiN 2 Si)− anion. The lithium (lithiosilyldiamide) 5 is formed when the donor [12] crown-4 is used for coordination of the ...
