Summary

Treatment of tetrachlorodisilanes RSiCl2SiC12R and the trichlorosilane (2, 6-iPr2C6H3)N(SiMe2-iPr)SiCl3 with sodium in liquid ammonia or an excess of liquid ammonia leads to the formation of tetraaminodisilanes RSi(NH2)2Si(NH2)2R and the triaminosilane (2, 6-iPr2C6H3)N(SiMe2-iPr)Si(NH2)3 respectively, in high yields. Methyltrichlorosilane reacts with sodium in liquid ammonia to yield the cluster (MeSi)6(NH)9. The aforementioned aminosilanes are stable against condensation and are also soluble in a variety of organic solvents, thus making these compounds useful starting materials for the preparation of a variety of metallasilazanes. The metallasilazanes resulting from the aminosilanes show interesting structural features. The Si-N-M framework in these compounds is made up of either cyclic or three-dimensional polyhedral core structures. The triaminosilane and the isoelectronic silanetriol (2, 6-iPr2C6H3)N(SiMe3)Si(OH)3 afford heteroadamantanes when reacted with the trimer [MeAIN(2, 6-iPr2C6H3)]3. The crystal structures of one of the tetraaminodisilanes, the imide and the metallasilazanes are reported.
