The oxidation of styrene by palladium salts in excess of HCl has been investigated in homogenous phase, using methanol as solvent. The degree of styrene conversion was followed polarographically. It was found that the reaction rate can be expressed by the rate equation corresponding to the transformation of a mononuclear complex with styrene coordinated to PdCl2-4, the kinetic term of which has the following form: w =k1[styrene][PdCl2-4]/[H3O+][Cl-]2.
