A metal-free regioselective sulfenylation of the α-CH3 group of ketones has been achieved in the presence of the α-CH2 or α-CH group using the cross dehydrogenative (CDC) strategy. Aldehydes also exhibit good selectivity forming the corresponding α-sulfenylated products. This efficient sulfenylation of ketones or aldehydes with thiones or heterocyclic thiols utilizes dimethyl sulfoxide (DMSO) as an
的α-CH的无金属区域选择性亚磺酰3组酮已在α-CH的存在下已经实现2使用交叉脱氢(CDC)的策略或α-CH基团。醛也表现出良好的选择性,形成相应的α-亚磺酰化产物。酮或醛与硫酮或杂环硫醇的这种有效的亚硫基化利用二甲基亚砜(DMSO)在碘存在下作为氧化剂。这种生态友好的方法使用了现成的廉价I 2和DMSO。通过合成Julia–Kocienski烯烃化中间体的前体已证明了该方法的应用。
