Abstract

The mixed addenda heteropoly acid H5PMo10V2O40 dissolved in 1,2-dichloroethane with tetraglyme, forming the (tetraglyme)3-H5PMo10V2O 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.
