摘要

首次通过交叉脱氢偶联（CDC）反应，在可见光诱导下建立了羟肟酸衍生物与2-芳基酰胺的区域选择性γ-C(sp3)-H乙烯化反应。这种远端γ-乙烯基化是通过羟基肟酸衍生物的光催化N-O键裂解原位产生的酰胺基自由基的1,5-氢原子转移（1,5- hat）来实现的。

Photoredox catalytic γ‑C(sp3)−H vinylation of hydroxamic acid derivatives via 1,5-hydrogen-atom-transfer-mediated cross-dehydrogenative coupling

A visible-light-induced regioselective γ-C(sp3)-H vinylation of hydroxamic acid derivatives with 2-aryl enamides was developed via cross-dehydrogenative coupling (CDC) reactions for the first time. This remote γ-vinylation was realized by the 1,5-hydrogen atom transfer (1,5-HAT) of the amidyl radicals that in situ generated through the potocatalytic N-O bond cleavage of hydroxamic acid derivatives.
