The reductive single electron transfer (SET) umpolung amination of aldehyde-derived hydrazones has been developed through visible-light-promoted photoredox catalysis. The ideal transformation of hydrazones into the corresponding hydrazonamide through selective carbon–hydrogen (C–H) bond functionalization represents one of the most step- and atom-economical methods. This SET umpolung strategy features
醛衍生的azo的还原单电子转移(SET)氨化胺是通过可见光促进的光氧化还原催化而开发的。通过选择性的碳氢键(C–H)键官能化将hydr理想地转化为相应的酰胺,是最经济,最经济的步骤之一。这种SET泵送策略的特点是条件温和且底物范围非常广,为指导CH-H胺化反应提供了全新的底物类别。
