Abstract

Vanadium compounds in a high oxidation state are considered to be versatile in oxidative transformations via one-electron transfer, but their synthetic utilization has been limited.'Our previous paper demonstrated that VO (OEt) Cl, catalyzes the ring-opening oxygenation of cyclic ketones in an alcohol under oxygem2 VO (OR) C12 appears to be a Lewis acid with oxidation capability. We here report that oxidative aromatization3 of a, p-unsatu-
