Abstract: Five kinds of thioether p-CH_3C_6H_4SR (R=n-C_4H_9, C_6H_(13), C_8H_(17), C_(10)H_(21), and C_(12)H_(25)) and their palladium complexes Pd(p-CH_3C_6H_4SR)_2Cl_2 were synthesized. The thermal decomposition of these complexes have been studied by using TG and DTG methods. It was found that the former two of the complexes firstly decompos into organic ligands and PdCl_2, then PdCl_2 to chlorine atoms and palladium; The latter three of complexes decompose into organic ligands chorine atoms and palladium almost simultaneously. Kinetic parameters such as activation energy E, frequency factor A and reaction order n were obtained using the Coats-Redfern and Freeman-Carroll methods. In addition, entropy of activation ΔS has also been calculated.
