The reaction of aminosilanes Me(4-x)Si(NHBun)x (x=1-4) with appropriate amounts of n-butyllithium gave the N-lithio derivatives Me(4-x)Si(NHBun)y(NLiBun)(x-y) (x=1, y=0 (I); x=2, y=0 (II), 1 (III); x=3, y=0 (IV), 1 (V), 2 (VI); x=4, y=0 (VII), 1 (VIII), 2 (IX), 3 (X)).Their infrared and 1H NMR spectra are reported, along with the 7Li NMR spectra of solutions of compounds I-IV and their complexes with PMDETA or TMEDA in n-pentane, diethyl ether, and THF.Inferences are drawn about the nature of solution species, and the analogy between tetra-imido anionic species Si(NR)4(4-) ("silazates") and the orthosilicate anion is explored.
