Oxovanadium(<scp>v</scp>)-catalyzed oxidative cross-coupling of enolates using O₂ as a terminal oxidant

Abstract

The oxovanadium(v)-catalyzed oxidative cross-coupling of enolates using O₂ as a terminal oxidant is reported, where a boron enolate and a silyl enol ether were employed as enolates. The redox behavior of V(v/iv) in this reaction under O₂ was investigated by ESR and ⁵¹V NMR experiments.
