Herein, a donor/acceptor-free carbene insertion reaction of an S–S bond through a radical process is presented. This catalyst-free reaction was thermally induced and provided the dithioketal products in moderate to high yields. A mechanism involving radical intermediates was proposed according to the computational study, and these intermediates were verified experimentally and intercepted for the first
在此,提出了通过自由基过程进行的 S-S 键的无供体/无受体卡宾插入反应。这种无催化剂反应是热诱导的,并以中等至高产率提供二硫缩酮产物。根据计算研究提出了涉及自由基中间体的机理,并首次通过交叉偶联反应对这些中间体进行了实验验证和截获。
