Abstract

3d-Metal-catalyzed tertiary C(sp³)–H bond activation has been a formidable challenge. Herein, a tertiary C(sp³)–H bond is smoothly activated by Ni–Al bimetallic catalysts for dual C–H annulation of formamides with alkynes, delivering a series of δ-lactams with a quaternary carbon up to 98% yield. Various tertiary C(sp³)–H bonds such as noncyclic, monocyclic and bridged-ring tertiary C(sp³)–H bonds are all compatible with the reaction.

镍-铝双金属催化三级 C(sp3)-H活化用于甲酰胺与炔烃的双 C-H 嵌合反应

3d金属催化三级C（sp3）-H键活化一直是一项艰巨的挑战。在此，Ni-Al 双金属催化剂顺利活化了三级 C(sp3)-H 键，用于甲酰胺与炔烃的双 C-H 环化反应，产生了一系列具有季碳的δ-内酰胺，收率高达 98%。各种三级 C（sp3）-H 键（如非环、单环和桥环三级 C（sp3）-H 键）均可与该反应相容。
