HX can be added to alkenes through a radical process to give anti-Markovnikov regioselectivity. The only difference is the addition of H2O2 to the reaction. In the initiation step, H2O2 homolytically cleaves to form 2 hydroxyl radicals. These radicals react with HCl to form Cl radicals. In the propagation steps, the Cl radical attacks the alkene on the less highly substituted end to form a more highly substituted radical. The new carbon radical then removes a hydrogen atom from HCl to generate the final product and another Cl radical.
