WebThe chlorine or bromine can substitute into the ring or into the methyl group. Substitution into the ring. Substitution in the ring happens in the presence of aluminium chloride (or aluminium bromide if you are using bromine) or iron, and in the absence of UV light. The reactions happen at room temperature.
