Abstract

The mixed addenda heteropoly acid H₆PMo₁₀V₂O₄₀ dissolved in 1,2-dichloroethane with tetraglyme, forming the (tetraglyme)₃-H₆PMo₁₀V₂O₄₀complex, catalyzes the aromatization of cyclic dienesat moderate temperatures in the presence of molecular oxygen. Dehydrogenations of exocyclic dienes such as limonene show that dehydrogenation is preceded by isomerization to their endocyclic isomers. Aromatization takes place by successive one-electron transfers and proton abstractions from the organic substrate to the heteropoly acid, the latter being reoxidized by dioxygen coupled with the formation of water.
