Preparations, properties, and vibrational spectra of some (dimethylamino)halogenosilanes

Abstract

We have prepared and characterised the new compounds SiH2Cl(NMe2), SiH2Br(NMe2), SiH2I(NMe2), and SiHCl2(NMe2). The vibrational spectra of the three (amino)monohalogenosilanes show dramitic changes on solidification, but those of the (amino)dichlorosilane are very similar in all three phases. These differences are discussed in the light of the formation of dimers in the crystalline solid of SiH2Cl(NMe2), and the presence of discrete monomers in the crystal of SiHCl2(NMe2). The n.m.r. spectra of the compounds, together with that of the monofluorosilane SiH2F(NMe2), are reported and discussed briefly.
