O2-mediated C(sp2)–X bond oxygenation: autoxidative carbon–heteroatom bond formation using activated alkenes as a linkage†
Abstract
Autoxidative carbon–heteroatom bond formation using activated alkenes as a linkage is described. Heteroatom (O, S) nucleophiles could be transformed into different kinds of valuable β-keto compounds via an O2-mediated C(sp2)–X bond oxygenation process, without using any external organic oxidants or metal catalysts.
