Previously published information regarding quaternary phosphonium salts can be found in HoubenWeyl, Vol.12/1, p79 and Vol.E 1, p491.[‌264‌] These compounds almost always exist as stable crystalline solids which can be prepared in various ways, for example by the addition of phosphines to electron-deficient alkenes,[‌265‌‌267‌] or, most commonly and conveniently, by the nucleophilic attack of a phosphine on an alkyl halide.[‌268‌]
