Abstract: The kinetics of thermolysis of RCo(Salen)Lcomplexes in methanol was studied by using UV-Vis spectrophotometry.The observable rate constants and the energy of activation were determined.The sequence of the rate constants is i-C3H7>i-C4H3>n-C4H9>n-C3H7>C2H5 and of the energy of activation is i-C3H7<n-C4H9<i-C4H9<n-C3H7<C2H5 The effects on thermolysis were discussed.
