An umpolung approach for the synthesis of unsymmetrical disulfides via sulfenium ion is reported. In situ generated electrophilic sulfenium ion from electron‐rich thiols reacted with second thiols to yield unsymmetrical disulfides. Using an iodine catalyst and 4‐dimethylaminopyridine (DMAP)/water as promoter, the target syntheses were achieved in one pot under aerobic condition.
报道了一种通过sulf离子合成不对称二硫化物的方法。原位富电子硫醇生成的亲电子sulf离子与第二硫醇反应生成不对称的二硫键。使用碘催化剂和4-二甲基氨基吡啶(DMAP)/水作为促进剂,在有氧条件下在一锅中即可完成目标合成。
