A novel Ni/photoredox-catalyzed acylation of aliphatic substrates, including simple alkanes and dialkyl ethers, has been developed. The method combines C–N bond activation of amides with a radical relay mechanism involving hydrogen-atom transfer. The protocol is operationally simple, employs bench-stable N-acyl imides as acyl-transfer reagents, and permits facile access to alkyl ketones under very mild conditions.

在光氧化还原/镍双催化下与 N-酰基酰亚胺的 C(sp3)-H 键酰化

已经开发了一种新型的 Ni/光氧化还原催化的脂肪族底物酰化，包括简单的烷烃和二烷基醚。该方法将酰胺的 C-N 键活化与涉及氢原子转移的自由基中继机制相结合。该协议操作简单，采用长期稳定的 N-酰基酰亚胺作为酰基转移试剂，并允许在非常温和的条件下轻松获得烷基酮。
