addition reaction of trialkylphosphites to in situ generated ortho-quinone methides (o-QMs) for the construction of diaryl phosphonates in moderate to excellent yields with 1.5 mol % catalyst. Diastereoselective synthesis of P-chiral phosphinate esters is achieved with the use of dialkyl phenylphosphonites.
