A catalytic three‐way rendezvous: Terminal alkynes undergo metal vinylidene formation, anti‐Markovnikov hydration to give a metal acyl complex, and conjugate addition to produce synthetically useful 1,4‐dicarbonyl compounds under ruthenium catalysis. This one‐pot three‐component coupling reaction is a useful platform for further exploration in alkyne functionalization.
催化三重集合点:末端炔烃经历金属亚乙烯基的形成,反马氏水合形成金属酰基配合物,并在钌催化下加成共轭物以生产合成上有用的1,4-二羰基化合物。这一单锅三组分偶联反应为进一步探索炔烃功能化提供了有用的平台。
