herein a catalyst‐free visible‐light photolytic protocol for the imidation of arenes and heteroarenes. N‐Bromosaccharin was identified as a viable and chemoselective nitrogen radical precursor that undergoes controllable homolytic cleavage under ambient light irradiation. The reaction can be applied to a number of arenes and heteroarenes with good chemo‐ and regioselectivity. Mechanistic studies revealed
我们在此描述了用于芳烃和杂芳烃的酰亚胺化的无催化剂可见光光解方案。N-溴糖精被认为是一种可行的化学选择性氮自由基前体,在环境光照射下会发生可控的均裂裂解。该反应可用于具有良好化学和区域选择性的多种芳烃和杂芳烃。机理研究表明,通过电子转移-质子转移(ET-PT)终止自由基链是反应的主要生产途径。
