Published: April 2022

Herein, we describe a novel Negishi-type cross-coupling of amides employing only cobalt bromide salt as the catalyst. This original reaction is highly tolerant to various glutarimide amides as well as organozinc coupling partners. These conditions also allow the performance of the cross-coupling reaction in an eco-compatible solvent such as ethyl acetate on a large scale.
