The Robinson Transposition Reaction. Conjugate-Addition/Intramolecular Wittig Reactions of Enolates with triphenylphosphonium Chloride

The phosphonium salt described reacts with certain enolates to produce dienyl sulfides that may be subsequently hydrolyzed to afford enones that are regiotransposed relative to the standard Robinson annulation product.
