Homogeneous and heterogeneous dehydrogenation reactions of cyclooctane with palladium(II) complexes as catalysts

A series of new palladium(II) complexes with heteroatomic chelating ligands (carboxylates and alcoholates) was synthesized. The catalytic activities of the palladium complexes were successfully tested for catalytic CH-activation reactions of cyclooctane. They gave TONs of 2.6–26.5 (300 °C, 16 h) in homogeneous solution and 4.6–21.4 (400 °C, 5 h) in heterogeneous reactions.
