The kinetics of the homolytic substitution of several trialkyltin iodides by iodine atoms are presented. Rate constants have been determined at three different temperatures and the following activation parameters calculated: A , E a , and Δ S ° ≠ . The observation that the activation energy, Δ G ≠ , is related to the driving force of the ion‐pair formation, leads to the conclusion that the charge‐transfer model is a valid approach for substitution in the reaction between R 3 SnI compounds and iodine atoms.
