difunctionalization of alkenes with diazo compounds and tert-butyl nitrite has been developed. The protocol provides an efficient approach to γ-oximino esters under mild conditions. Significantly, this transformation not only shows the good compatibility of nucleophilic diazo compounds and electrophilic tert-butyl nitrite but also displays diazo compounds generating alkyl radicals that preferred addition to alkenes
已经开发了用重氮化合物和亚硝酸叔丁酯对烯烃进行可见光光催化区域选择性双官能化。该协议提供了一种在温和条件下对 γ-肟酯的有效方法。值得注意的是,这种转变不仅显示出亲核重氮化合物和亲电子亚硝酸叔丁酯的良好相容性,而且还显示重氮化合物产生烷基自由基,烷基自由基优先加成烯烃而不是亚硝基自由基。
