A simple and efficient synthesis of cyclopentadienones via palladium-catalyzed cyclocarbonylation of alkynes under atmospheric pressure of carbon monoxide has been developed. The transformation was carried out under mild and ligand-free conditions, a wide range of substrates and exceptional functional group tolerance.
已经开发了在一氧化碳的大气压下通过钯催化的炔烃环羰基化的一种简单而有效的合成环戊二烯酮的方法。转化是在温和且无配体的条件下,多种底物和出色的官能团耐受性下进行的。
