Abstract An efficient synthesis of vinyl sulfones 3a-o from aryl methyl ketones 2 bearing an electron withdrawing group and the phosphonic ester 1 under sonochemical conditions is reported. These compounds are generally obtained as an E/Z mixture. Formation of the allyl sulfones 4 is also observed.
摘要 报道了在声化学条件下由带有吸电子基团的芳基甲基酮 2 和膦酸酯 1 有效合成乙烯基砜 3a-o 的方法。这些化合物通常以 E/Z 混合物的形式获得。还观察到烯丙基砜4的形成。
