thiols and thiones. The reaction occurs at the nitrogen center over the sulfur, leading to the amination against the traditional sulfenylation. A wide variety of allylic and benzylic alcohols serve as coupling partners. This method showed a good tolerance toward 1H-tetrazole-5-thiol, 5-methyl-1,3,4-thiadiazole-2-thiol, benzo[d]thiazole-2(3H)-thione, and benzo[d]oxazole-2(3H)-thione derivatives.
使用杂环硫醇和硫酮已开发出碘催化的化学键形成的C–N键。该反应发生在硫上方的氮中心,从而导致了针对传统亚磺酰化的胺化反应。各种各样的烯丙基和苄基醇用作偶联伴侣。该方法对1 H-四唑-5-硫醇,5-甲基-1,3,4-噻二唑-2-硫醇,苯并[ d ]噻唑-2(3 H)-硫酮和苯并[ d ]具有良好的耐受性]恶唑-2(3 H)-硫酮衍生物。
