The development of efficient methods for the metathesis and phosphorylation reactions of disulfide compounds is of widespread interest due to their important synthetic utility in polymer, biological, medicinal and agricultural chemistry. Herein, we demonstrate the use of N‐heterocyclic carbenes (NHCs) as versatile organocatalysts to promote these challenging reactions under mild conditions. This metal‐
由于二硫化物化合物在聚合物,生物,药物和农业化学中的重要合成用途,因此开发有效的二硫化合物的复分解和磷酸化反应方法的方法引起了广泛的兴趣。本文中,我们证明了使用N-杂环卡宾(NHC)作为通用有机催化剂在温和条件下促进这些具有挑战性的反应。这种不含金属和氧化剂的方案操作简单,反应时间非常短。NMR研究和高水平的从头算计算也阐明了这些反应中NHC的亲核性和碱性之间的相互作用。
