Studies in homogeneous catalysis: Copper-phenanthroline complexes as catalysts for the oxidation of methanol

Autor: C. J. Gaasbeek, W. Brackman

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 85:242-256

Copper phenanthroline complexes are catalysts for the oxidation of methanol by oxygen at 30-45 °. A feature of the reaction is that it shows an induction period unless started with small amounts of H2O2 or cuprous ion. During the reaction the system

Studies in homogeneous catalysis: The stepwise degradation of unbranched aldehydes to acetaldehyde and formate units by copper-catalysed oxidation

Autor: C. J. Gaasbeek, W. Brackman, P. J. Smit

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 85:437-445

Straight-chain aliphatic aldehydes of at least three carbon atoms can be catalytically in methanol solutions of copper-pyridine complexes and triethylamine by oxygen at 40 °C. In this oxidation the carbon atoms, starting with the carbon atom, are su

The stable radical di-tert-butyl nitroxide is found to catalyse various oxidation reactions effected by cupric complexes, and to promote various oxidations with oxygen catalysed by copper complexes. Examples of its activity are found in the formation

Chemistry and spectroscopy in strongly acidic solutions. Part XXXI: Rates of carbonylation of stabilized carbonium ions

Autor: H. Hogeveen, C. J. Gaasbeek

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 89:395-401

The rate constants of carbonylation of some unsaturated carbonium ions and cyclopropylcarbonium ions have been determined. The results indicate that bicyclic homoallylic ions, e.g. the 7-norbornadienyl ion, are stabilized by non-classical electron de

Studies in homogeneous catalysis: Di-tert-butyl nitroxide as promoter of the copper-catalysed oxidation of methanol by oxygen

Autor: C. J. Gaasbeek, W. Brackman

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 85:257-267

The oxidation of methanol by oxygen, catalysed by copper-phenanthroline complexes and promoted by the stable radical di-tert-butyl nitroxide, has been studied. The results are discussed in connection with the previously studied oxidation of methanol
