Cover Picture: Efficient Vanadium‐Catalyzed Aerobic C−C Bond Oxidative Cleavage of Vicinal Diols (Adv. Synth. Catal. 17/2018)

Abstract

The inside cover picture, provided by Giulia Licini, Carles Bo and coworkers illustrates the highly chemoselective aerobic oxidative cleavage of 1,2‐diols to the corresponding carbonyl derivatives catalyzed by vanadium‐aminotriphenolate complexes. This catalytic method works with a large variety of glycols, linear or cyclic, with aromatic or aliphatic substituents. Pre‐association of the substrate to the metal center, followed by a two‐electron oxidation mechanism, yields the carbonyl derivatives and a reduced VIII metal complex, which is rapidly oxidized back to the catalyst by O2.
