Three new visible‐light‐promoted functionalizations of benzotriazole substrates were discovered using a mechanism‐based screening method. ortho‐Thiolated, borylated, and alkylated N‐arylbenzamide products were obtained under mild reaction conditions in a new denitrogenative synthetic approach to functionalized aniline derivatives. The functional group tolerance of the borylation reaction was further
使用基于机理的筛选方法发现了苯并三唑底物的三个新的可见光促进的官能化。在温和的反应条件下,采用新的脱氮合成方法对官能化的苯胺衍生物进行了邻-硫代,硼化和烷基化的N-芳基苯甲酰胺产品。在基于添加剂的耐用性筛选在光催化转化中的首次应用中,进一步分析了硼酸酯化反应的官能团耐受性。所有功能化都是通过光催化引发的链机制进行的,如确定反应量子产率和进行Stern-Volmer分析所表明的。
