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

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.
