thiophenols/thiols as thiolating agents. Specifically, metal catalysts and external chemical oxidants are not needed in the reaction for the formation of β-formyloxy sulfides, and these sulfides can be further converted to (E)-vinyl sulfones via the Selectfluor-mediated oxidation–olefination. Notably, on the basis of this electrochemical oxidation strategy, β-hydroxy sulfide, β-formyloxy sulfoxide, β-formyloxy
我们报告了使用市售苯硫酚/硫醇作为硫醇化剂的 PhB(OH) 2促进的苯乙烯电化学硫化-甲酰氧基化反应。具体而言,在形成 β-甲酰氧基硫化物的反应中不需要金属催化剂和外部化学氧化剂,这些硫化物可以通过 Selectfluor 介导的氧化-烯化进一步转化为 ( E )-乙烯基砜。值得注意的是,基于这种电化学氧化策略,β-羟基硫化物、β-甲酰氧基亚砜、β-甲酰氧基砜和(E)-乙烯基亚砜也可以很容易地制备。
