visible‐light‐induced photocatalytic reduction of aromatic, heteroaromatic, aliphatic and sulfonyl azides to the corresponding amines using hydrazine hydrate as a reductant. The reaction shows excellent conversion and chemoselectivity towards the formation of the amine without self‐photoactivated azo compounds. In the adopted strategy, CdS not only accelerates the formation of nitrene through photoactivation of
CdS sheet-rGO纳米复合材料作为非均相光催化剂,可以使用水合肼作为还原剂,将可见光诱导的芳族,杂芳族,脂族和磺酰基叠氮化物光催化还原为相应的胺。该反应在没有自光活化偶氮化合物的情况下,对胺的形成显示出优异的转化率和化学选择性。在所采用的策略中,CdS不仅通过叠氮化物的光活化促进了亚硝基的形成,而且在一定程度上增强了叠氮化物的分解,从而完全抑制了偶氮化合物的形成。开发的CdS sheet-rGO纳米复合催化剂非常活泼,在用40 W简易家用CFL灯照射下可提供出色的结果。
