The mixed addenda heteropoly acid H{sub 5}PMo{sub 10}V{sub 2}O{sub 40} dissolved in 1,2-dichloroethane with tetraglyme, forming the (tetraglyme){sub 3}-H{sub 5}PMo{sub 10}V{sub 2}O{sub 40} complex, catalyzes the aromatization of cyclic dienes at 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.
