Some metal halide–phosphorus halide–alkyl halide complexes. Part I. Reactions with boron, aluminium, silicon, germanium, and tin halides

Abstract

The reaction systems metal chloride–phosphorus trichloride–tert-butyl chloride (metal = Al, B, Si, Ge, or Sn) and metal chloride–methyldichlorophosphine-tert-butyl chloride (metal = B, Ge, or Sn) have been investigated. Solid products were obtained in each case with the exception of silicon and germanium. These solids have been characterised by vibrational spectroscopy as ionic complexes of alkylchlorophosphonium cations with the univalent anionic species AlCl₄^–, BCl₄^–, and SnCl₅^–.
