Carbon–sulfur bond-formation reactions are applied widely in organic synthesis and chemical biology. Hydrothiolation of alkenes provides a direct way to build carbon–sulfur bonds. Most known methods proceed via radical processes and result in anti-Markovnikov-type products. Herein, we demonstrate that I2 catalyzes the hydrothiolation of alkenes and provides Markovnikov-type products in good to excellent
碳硫键形成反应在有机合成和化学生物学中有着广泛的应用。烯烃的氢硫醇化提供了建立碳硫键的直接方法。大多数已知方法通过激进过程进行并产生反马尔可夫尼科夫型产品。在此,我们证明 I 2催化烯烃的氢硫醇化反应,并以良好至优异的收率提供 Markovnikov 型产品。滴定研究表明硫醇被 I 2通过卤键激活。这种无金属反应具有绿色温和、功能耐受性高、底物适用范围广、原子经济等优点。它的应用在肽合成中得到进一步证明。
