The kinetics of Zn(II), Cd(II), and Hg(II) incorporation into meso tetrameta‐tolueneporphyrin (H 2 T( m ‐CH 3 )PP) in acetone have been studied by means of stopped‐flow method. A unified reaction mechanism was proposed and the kinetic parameters were obtained by nonlinear least‐square methods. The effect of ionic strength (I) on Cd(II)/H 2 T( m ‐CH 3 )PP was investigated. It has been found that there is a negative kinetic salt effect and the relationship of rate constants with ionic strength was obtained. Some solvent effects have also been investigated in this article. © 1998 John Wiley & Sons, Inc. Int J Chem Kinet 30: 277–283, 1998.
