Zn(II)–Cr(III) Mixed Oxide as Efficient Bifunctional Catalyst for Dehydroisomerisation of a-Pinene to p-Cymene

Zn(II)–Cr(III) mixed oxide possessing acid and dehydrogenation functions is an efficient, noble-metal-free catalyst for the one-step dehydroisomerisation of a-pinene to p-cymene. This reaction is a good example of the use of heterogeneous multifunctional catalysis for the conversion of renewable feedstock into value-added chemicals.
