Previously published information regarding quaternary phosphonium salts can be found in Houben–Weyl, Vol. 12/1, p 79 and Vol. E 1, p 491.[‌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,[‌265‌–‌267‌] or, most commonly and conveniently, by the nucleophilic attack of a phosphine on an alkyl halide.[‌268‌]
