The kinetics of the addition of iodine to cyclohexene, 3-methylcyclohexene, and 1-hexene in the liquid phase under the irradiation of light have been studied. The reaction rate was measured by following the decrease in the absorbance at 524 nm due to molecular iodine. It was observed that iodine concentration decreased very slowly in the dark according to the reaction C+I2→C·I2. The kinetic results of photoreaction show the occurence of the reaction C·I+I·→C·I2. In above reactions C·I and C·I2 denote iodine atom-olefin and iodine molecule-olefin charge-transfer complexes, respectively. It is possible to determine kinetically I2-olefin charge-transfer equilibrium constants.
