An iridium‐catalyzed direct CH amidation of weakly coordinating substrates, in particular of those bearing ester and ketone groups, under very mild conditions has been developed. The observed high reaction efficiency was achieved by the combined use of acetic acid and lithium carbonate as additives.
已经开发了在非常温和的条件下弱配位的底物(特别是带有酯基和酮基的底物)的铱催化直接CH酰胺化反应。通过组合使用乙酸和碳酸锂作为添加剂,可以实现较高的反应效率。
