An efficient and practical approach has been developed for synthesizing phosphonates phosphine oxides from Morita–Baylis–Hillman (MBH) adducts through the alkylation of trialkylphosphites ethoxydiphenylphosphine using phosphonium salts derived MBH as powerful alkylating agents.The proceeds via a Michaelis–Arbuzov mechanism. This regiospecific reaction combining SN2' + = SN2 pathway was conducted under refluxing in CHCl3, resulting isolation products good yields. Une approche efficace et pratique été développée pour synthétiser des oxydes de à partir d'adduits (MBH), par d'éthoxydiphénylphosphine en utilisant sels dérivés comme puissants agents alkylants.L'alkylation se déroule le mécanisme Michaelis–Arbuzov. Cette réaction régiospécifique combinant les voies réalisée dans conditions reflux ce qui permis d'isoler produits avec bons rendements.
