We developed a method for the synthesis of alkynyl amides via the carbonylation of alkynoic acids and C-N activation of tertiary amines. The reaction of alkynoic acid and tertiary amine with carbonmonoxideusing a palladium catalyst in the presence of oxygen, KI, and K3PO4, gave the desired alkynyl amides in good yields.
我们开发了一种通过炔酸的羰基化和叔胺的CN活化合成炔基酰胺的方法。在氧,KI和K 3 PO 4的存在下,使用钯催化剂使炔酸和叔胺与一氧化碳反应,以良好的收率得到所需的炔基酰胺。

efficient approach for direct carbamoylation of terminal alkynes with formamides affording propiolamides has been developed by copper-catalyzed oxidative cross coupling of C(sp)-H and C(sp2)-H bonds in the presence of a pincer ligand with two imidazolyl groups. The catalytic reaction is compatible with diverse functional groups but sensitive to the electronic effect of terminal alkyne and the steric effect
