decarbonylative Sonogashira coupling of terminal alkynes with carboxylic acids was achieved through palladium catalysis. This reaction did not use overstoichiometric oxidants, thus overcoming the homocoupling issue of terminal alkynes. Under the reaction conditions, a wide range of carboxylic acids including those bioactive ones could couple readily with various terminal alkynes, thus providing a relative general
末端炔烃与羧酸的直接脱羰Sonogashira偶联是通过钯催化实现的。该反应没有使用化学计量过量的氧化剂,因此克服了末端炔烃的均偶联问题。在反应条件下,包括那些具有生物活性的羧酸在内的各种羧酸都可以很容易地与各种末端炔烃偶联,因此提供了一种相对通用的制备内部炔烃的方法。
