Abstract

Exchange between dihalogenosilanes and hydrogen halides leads to the formation of mixed dihalogenosilanes; ¹H chemical shifts and ²⁹SiH coupling constants have been obtained, and equilibrium constants measured for the reactions SiH₂X₂+ SiH₂Y₂ 2SiH₂XY. The usual additivity relationships are not well obeyed by the n.m.r. parameters in these systems. Evidence is presented for the existence of the species XSiH₂CN (X = Cl, Br, I). The Raman spectrum of SiH₂ICI has also been obtained.
