The reaction of iodine with allyl alcohol has been studied in a static system, following the absorption of visible light by iodine, in the temperature range 150‐190°C and in the pressure range 10‐200 torr. The rate‐determining step has been found to beand k 3 is consistent with the equationFrom the activation energy and the assumption E ‐3 = 1 ± 1 kcal mol −1 , it has been calculated thatkcal mol −1 . The stabilization energy of the hydroxyallyl radical has been found to be 11.4 ± 2.2 kcal mol −1 .
