An efficient method for synthesis of 1,3-diynes through the CuI/1,10-phenanthroline-catalyzed oxidative decarboxylative homocoupling of aryl pioprolic acids in aqueous DMF has been developed. The catalytic system was suitable for a variety of arylpropiolic acids, and the corresponding 1,3-diynes could be prepared in high yields. The catalytic system was recovered from the organic products by filtration
已经开发了一种通过 CuI/1,10-菲咯啉催化的芳基吡丙酸在 DMF 水溶液中的氧化脱羧均偶联合成 1,3-二炔的有效方法。该催化体系适用于多种芳基丙炔酸,可以高产率制备相应的1,3-二炔。通过过滤从有机产物中回收催化体系,其含水 DMF 滤液即使在至少使用四次循环后仍保持良好的活性。
