nitrenium (NHN) salts, the analogues of N-heterocyclic carbenes, have attracted considerable interest. However, relatively little is known about their catalytic ability beyond their Lewis acid catalysis. Herein, we describe that NHNs can serve as catalytic electron acceptors for charge transfer complex photoactivations. We showcase that, under blue light irradiation, the NHN salts could catalyze the
N-杂环氮 (NHN) 盐是 N-杂环卡宾的类似物,引起了相当大的兴趣。然而,对于它们在路易斯酸催化之外的催化能力知之甚少。在这里,我们描述了 NHNs 可以作为电荷转移复合物光活化的催化电子受体。我们展示了在蓝光照射下,NHN盐可以催化芳基卤化物生成芳基自由基。
