A copper-catalyzed decarboxylative cross-coupling reaction of propiolic acids with terminal alkynes is developed leading to unsymmetric 1,3-conjugated diynes under mild conditions. This method provides a novel decarboxylative cross-coupling for sp-sp bond formation. Compared to organic halides, only carbon dioxide is produced as by-products in this approach.
开发了铜催化的丙酸与末端炔烃的脱羧交叉偶联反应,导致在温和条件下产生不对称的1,3-共轭二炔。该方法提供了用于sp-sp键形成的新颖的脱羧交叉偶联。与有机卤化物相比,这种方法仅产生二氧化碳作为副产物。
