A convenient general method is reported for the synthesis of α-aryl substituted ethylphosphonic acids and esters by hydrogenation of α-aryl substituted ethenylphosphonic acids and esters. Racemic α-arylethylphosphonic acids and esters were prepared in 70–88% yield under palladium-assisted transfer hydrogenation conditions using ammonium formate. Asymmetric hydrogenation of α-arylethenylphosphonic acids
已经报道了一种通过氢化α-芳基取代的乙烯基膦酸和酯来合成α-芳基取代的乙基膦酸和酯的常规方法。外消旋α-芳基乙基膦酸和酯是在甲酸辅助下,在钯辅助转移氢化条件下以70-88%的收率制备的。使用手性Ru(II)催化剂对α-芳基乙烯基膦酸进行不对称加氢可生成对映体过量高达86%的α-芳基乙基膦酸。
