摘要：

The isotopomerization of the (Fe(COa)(COb)(PMe3)2MeI)-C-13 complex was studied in various solvents. The kinetic and thermodynamic parameters suggest that the isotopomerization proceeds via ionization of the Fe-I bond, rearrangement of the formed ion-pair, and reentry of the iodide ligand. This behavior supports a CO insertion mechanism proceeding via direct substitution of the iodide with CO and formation of an ionic intermediate.
