Abstract
The effect of the nature of the anion in a palladium salt on a coupled process involving the oxidation of CO and hydrocarboxylation of cyclohexene in the PdX2-CuBr2-THF-H2O system was studied. The kinetics was investigated under the steady-state conditions. The kinetic isotope effects (H2O/D2O) for the rates of formation of CO2 and cyclohexanecarboxylic acid were measured. The mechanism of the coupled processes of hydrocarboxylation of cyclohexene involving the formation of palladium hydride complexes and their transformations was suggested. The kinetic model of the processes was obtained.
