A highly effective copper catalyst has been developed that promotes the insertion of carbon dioxide into the CH bond of terminal alkynes under unprecedentedly mild conditions. For the first time, propiolic acids can thus be synthesized in excellent yields from alkynes and carbon dioxide in the presence of the mild base cesium carbonate. The catalyst, (4,7-diphenyl-1,10-phenanthroline)bis[tris(4-fl
已经开发出一种高效的铜催化剂,该催化剂在前所未有的温和条件下可促进二氧化碳插入末端炔烃的CH键中。因此,在温和的碱式碳酸铯的存在下,炔烃和二氧化碳可以以极高的收率合成丙酸。该催化剂,(4,7-二苯基-1,10-菲咯啉)双[三(4-氟苯基)膦]铜(I)硝酸盐,易于获得并且对空气和水相对稳定。
