Oxidative dehydrogenation of cyclohexene to benzene by oxygen, catalyzed by a palladium cluster
- 50 Downloads
A reaction mechanism is proposed for the oxidative dehydrogenation of cyclohexene by oxygen to benzene, catalyzed with a (PPh)2Pd5 cluster, including reversible complexing of cyclohexene with (PPh)2Pd5, the rupture of the C-H bond of coordinated cyclohexene, and the reaction of the resulting complex and O3 with the generation of reaction products and reversible interaction of (PPh)2Pd5 with the benzene.
The equilibrium constants of (PPh)2Pd5 with cyclohexene and benzene, as well as the rate constant for the rupture of the C-H bond of the coordinated cyclohexene have been determined.
