Abstract

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 be

and k~3~ is consistent with the equation

From the activation energy and the assumption E~‐3~ = 1 ± 1 kcal mol^−1^, it has been calculated that
