Reactions of tin(IV) chloride with silyl compounds. Part I. Reactions with inorganic silyl compounds

Abstract

The reactions between SnCl₄ and (SiH₃)_nX have been investigated [n= 1, X = H, F, Cl, Br, SiH₃, Mn(CO)₅, or Co(CO)₄; n= 2, X = 0 or S; n= 3, X = N or P]; the reaction with (Me₂SiH)₂O was also investigated. With SiH₄, Si₂H₆, SiH₃F, SiH₃Cl, [SiH₃Mn(CO)₅], and (SiH₃)₃N, reaction led to monochlorination at silicon, and spectroscopic parameters for the compounds SiH₂FCl, [SiH₂ClMn(CO)₅], ClSiH₂N(SiH₃)₂, (ClSiH₂)₂NSiH₃, and (ClSiH₂)₃N, all prepared by this route, are reported. For the amines, ²⁹Si and ¹⁵N chemical shifts were measured by heteronuclear double resonance. Reactions with other silyl compounds led to the formation of SiH₃Cl, although some evidence was obtained for the formation of intermediate trichlorostannyl species.
