Abstract: | The kinetics of the reaction of MoOS2(S2CNR2)2 (R = CH3, C2H5, n-C3H7) with PPh3 have been studied using a Stopped-flow method. It was found that these MoOS2(S2CNR2)2 complexes react with PPh3 in the form of an irreversible second-order reaction. The rate constants at 25°C are respectively 48.4, 23.8, and 20.8 mol?1 dm3 s?1 and the activation energies are 4.8, 4.9, and 5.0 Kcal/mol with R = CH3, C2H5, and n-C3H7. |
