Summary

The reactivity of some trichlorosilane-derived silazanes has been studied. Treatment of 2-amino-1, 3-bis(trimethylsilyl)-1, 3-diaza-2-silacyclopentane (2) with two equivalents of n-butyllithium results in the formation of its hexameric N, N-dilithium derivative 3, the structure skeleton of which is best described as a singly truncated but lithium-centered rhombic dodecahedron of eight lithium and five nitrogen atoms. Reduction of Si-Cl-containing silazanes with lithium alanate opens a straightforward access to aminoalanes. Bis[(tert-butylamino)chloroalane] (8), bis[(tert-butyl-amino)alane] (9), and 1, 3-di-tert-butyl-ls4, 3s4-diaza-2s4, 604-dialumina[2.1.l]bicyclohexane (10) have been synthesized and structurally characterized.
