It was found that hydrophilic organic solvent, added to aqueous PdCl2 solution to increase the solubility of alkene, affects both parallel processes taking place during the reaction of 1-alkenes with PdCl2, i.e. the isomerisation of 1-alkene to internal n-alkenes and the oxidation of alkenes to carbonyl compounds; the solvent can facilitate either both processes (alcohols) or only one of the processes (acetic acid - isomerisation, N,N-dimethylformamide - oxidation), eventually it can retard both or one of processes (acetonitrile - oxidation, dioxane - isomerisation, dimethyl sulphoxide - isomerisation and oxidation). On using 2-methoxyethanol as the solvent, the oxidation of 1-octene can be correlated by the same rate equation as the oxidation of styrene or ethylene.
