Substituted allyl diphenylphosphine oxides as radical allylating agents

(Chemical Equation Presented) Radically useful: The radical addition of dithiocarbonates to branched allyl diphenylphosphine oxides can be followed by elimination of a diphenylphosphinoyl radical, thereby giving rise to allylated products (see scheme; Phth = phthalimido). Highly functionalized structures can thus be rapidly assembled under mild conditions and from cheap and readily available substrates and reagents.
