Direct radical oxyphosphorylation of styrenes with diarylphosphine oxides and dialkylphosphites mediated by Mn(OAc)3 is described. The solvent played a key role in this selective difunctionalization reaction.

)‐Homoallylic Phosphonates
A first simple palladiumcatalyzedallylation of vinylethylene carbonates with β‐ketophosphonates has been developed. This method provides access to (Z)‐tri‐ and tetrasubstituted homoallylic phosphonates with exclusive regioselectivity, chemoselectivity and (Z)‐stereoselectivity. The reaction tolerates a wide substrate scope of vinylethylene carbonates and β‐ketophosphonates with electron‐donating
Direct radical acetoxyphosphorylation of styrenes mediated by Mn(OAc)(3) with diphenylphosphine oxide and dialkyl phosphites was described, and a new type of difunctionalization of alkenes was achieved.
