A new sulfenylation reaction has been established, stereoselectively affording 37 examples of α-arylthio-α,β-unsaturated ketones with generally good yields via a metal-free three-component reaction of α-thiocyanate ketones with diaryliodonium salts and 1,2-dicarbonyls. The reaction enabled multiple bond-forming events including C(sp²)–S formation to provide a high-efficient and practical method toward α-arylthio-α,β-unsaturated ketones. The reasonable mechanism for forming α-arylthio-α,β-unsaturated ketones was proposed.

用于合成不含金属的碱促进的亚磺酰化α -芳硫基α，β不饱和酮

已经建立了新的亚磺酰化反应，通过α-硫氰酸酯酮与二芳基碘鎓盐和1,2-二羰基的无金属三组分反应，立体选择性地获得了37种α-芳硫基-α，β-不饱和酮的实例，通常收率良好。。该反应使包括C（sp ²）–S形成在内的多个键形成事件能够提供一种针对α-芳硫基-α，β-不饱和酮的高效实用方法。提出了形成α-芳硫基-α，β-不饱和酮的合理机理。
