A cobalt-catalyzed reaction protocol is developed to achieve the intramolecular oxidative C(sp)-H/N-H carbonylation of aliphatic amides with CO. Various substituted propanamides are selectively transformed into corresponding succinimides in good to high yields. Notably, predominant selectivity for the carbonylation at the α-methyl groups of linear aliphatic amides is observed in this reaction system.
发展了一种钴催化反应体系,实现了 CO 参与的脂肪族酰胺的分子内氧化 C(sp)-H/N-H 羰基化反应。各种取代的丙酰胺可被选择性地转化为相应的琥珀酰亚胺,收率良好至较高。值得注意的是,在该反应体系中观察到线性脂肪族酰胺的α-甲基碳原子的羰基化反应具有主要的选择性。
