Hydrocarboalcoksilation of cyclohexene is of practical interest as the reaction, presenting the basis of the receipt of an important intermediate product in the synthesis of pharmaceuticals - methylcyclohexanecarboksilat [1]. In this regard, the research of the activity of the catalysts, used for this purpose, is the actual problem. In the context of this problem and in strictly comparable conditions, we studied the activity of palladium catalysts Pd(PPh3)2Cl2, PdCl2 and (CH3COO)2Pd, promoted by means of free triphenylphosphine and p-toluenesulfonic acid (TsOH), in the reaction of hydrocarbomethoksilation of cyclo-hexene at constant concentrations of precursors.
