Abstract
Di(-tert.-butylamino)dichlorosilane reacts with an excess of methylami ne to give di(-tert.-butylamino)di(methylamino)silane 1, (Me(3)CHN)(2) Si(NHMe)(2). The dilithiumderivative 2, (Me(3)CHN)(2)Si(NLiMe)(2), is obtained in the reaction of 1 with a molar ratio 1:2 of n-buli in n-he xane. In absence of donorsolvents 2 crystallizes tetrameric. Lithium i s coordinated in three different ways and substitutes the methylamino- hydrogen. In the crystal structure two eight-membered(NLiNSi)(2)-rings are connected by two lithium.
