A novel and efficient approach for the C(sp)-H bond carbonylation of benzamides has been developed using stable and inexpensive Co(OAc)·4HO as the catalyst and the commercially available and easily handling azodicarboxylates as the nontoxic carbonyl source. A broad range of substrates bearing diverse functional groups were tolerated. This is the first example where cobalt-catalyzed C(sp)-H bond carbonylation occurs with azodicarboxylate as the carbonyl source.
一种新颖、高效的酰胺 C(sp)-H 键羰基化方法已经被开发出来，使用稳定且廉价的 Co(OAc)·4HO 作为催化剂，以及商业上可用且易于处理的偶氮二甲酸酯作为无毒羰基源。该方法容忍广泛的带有各种不同官能团的底物。这是首例以偶氮二甲酸酯作为羰基源，钴催化 C(sp)-H 键羰基化反应的例子。
