Diethyl acetyl and diethyl benzoyl phosphites reacted with propenal and 3-buten-2-one to give 1,4-addition products respectively. While the reaction of diethyl acetyl phosphite with 2-butenal and 2-methyl- and 3-phenylpropenals gave 1,2-addition products exclusively.
A high-yielding and convenient procedure for the efficient conversion of α-hydroxyphosphonates to α-acetyloxyphosphonates using acetic anhydride in the presence of catalytic amounts of copper triflate is described.

efficient, and new method has been developed for the synthesis of alpha-acetoxyphosphonates from aldehydes through a one-pot reaction of aldehydes with diethylphosphite in the presence of acetic anhydride under solvent-free conditions using magnesium oxide. This method is easy, rapid, and high yielding for the one-potsynthesis of alpha-acetoxyphosphonates from aldehydes.
