Oxidation of cyclohexene and α-pinene with O2-H 2 mixture in the presence of supported platinum or palladium catalysts

Oxidation of cyclohexene and α-pinene with an O2-H 2 mixture in the catalytic systems containing Pt or Pd and heteropoly compounds (HPC) was studied. The main oxidation products are epoxides, allyl alcohols, and ketones. The highest yield of the oxidation products was obtained in the presence of the platinum catalyst in combination with HPC PW11 or PW11Fe. The reaction mechanism was proposed. A relationship between the HPC composition and the nature of intermediates involved in oxidation was examined.

INVESTIGATION OF COMPOUNDS OF THE o-METHANE SERIES. XII. INVESTIGATION OF THE COMPOSITION OF THE PRODUCTS FROM PYROLYSIS OF VERBENENE

During the pyrolysis of verbenene the opening of the cyclobutane ring occurs at the C1-C7 and C5-C7 bond with the formation of terpene compounds of the o- and p-methane series.The latter were submitted to secondary reactions of isomerization and disproportionation of hydrogen, leading to the reduction of monocyclic and bicyclic terpene and aromatic hydrocarbons and unsaturated compounds of the isobutylcyclohexane series.

Palladium(II)-catalyzed asymmetric oxidative cyclization of 2-allylphenols in the presence of copper(II) acetate and molecular oxygen. Study of the catalysis of the Wacker-type oxidation

The intramolecular oxidative cyclization of trans-2-(2-butenyl)phenol (2) using (+)-(3,2,10-η-pinene)palladium(II) acetate (1) in the pressure of Cu(OAc)2 and O2 has been studied in order to gain insight into the catalysis of the Wacker-type oxidation. The main results obtained are as follows: (1) the catalytically active Pd(II) species which is different from complex 1 is formed during the reaction, (2) the chiral pinanyl ligand is retained by the catalyst throughout the reaction, and (3) the catalyst consists of copper and palladium linked with an acetate bridge. These results cannot be accounted for by the conventional Wacker-type catalysis involving the reoxidation of palladium(0). A hydroperoxopalladium(II) species coupled with copper(II) acetate is most likely the active catalyst in the present reaction. A mechanism for the enantioselection is also described in comparison with the results obtained by the oxidative cyclization of cis-2-(2-butenyl)phenol.
