Vanadium for victory The cover picture shows that an isolated monomeric vanadium-oxide species can promote the isomerization of allylic alcohols under liquid-phase conditions. In their Communication on p. 2879 ff., K. Kaneda et al. present the creation and characterization of the isolated monomeric vanadium species on silica surface (V/SiO2) and the high catalytic activity of V/SiO2 for various allylic alcohols, including under scaled-up and solvent-free reaction conditions. This heterogeneous catalyst also exhibits high reusability with no drop in activity. Our results highlight that the monomeric vanadium species plays a crucial role in the isomerization.
