Kinetic and quantum-chemical investigation of fac→mer isomerization of cobalt(III) trisaminoethoxide
The kinetics of the fac→mer isomerization of cobalt(III) trisaminoethoxide were studied. The acceleration of the reaction with decrease of the pH of the solution is explained by the formation of a reactive monoprotonated form of the complex. The direction of isomerization agrees with quantum-chemical calculations performed at the B3LYP/6-31G** level. The rate constants and activation parameters of the process were obtained. The mechanism of isomerization is discussed.
