A direct di-sulfenylation of methyl ketones with disulfides mediated by KOH-DMSO superbase system has been developed. This reaction provides an efficient route to α,α-dithioketones, which has the advantages of readily available non-prefunctionalized substrates, good functional group tolerance, excellent yields as well as high selectivity. In a single operation, two CS bonds are simultaneously built
已经开发了由 KOH-DMSO 超碱体系介导的甲基酮与二硫化物的直接二苯基化反应。该反应为制备α,α-二硫酮提供了一条有效的途径,具有易于获得的非预官能化底物、良好的官能团耐受性、优异的收率和高选择性等优点。在一次操作中,在温和的反应条件下,两个 C S 键同时建立在同一个碳原子上。
