The regioselectivity of the addition of molecular bromine chloride to alkenes is dependent on both the steric and electronic effects of the alkyl substituent. In contrast, the regioselectivity of the addition of dichlorobromate (1−) ion to alkenes is controlled mainly by the steric effect of the substituent.

The first example of the synthesis of m-alkylphenols via a ruthenium-catalyzed CAr–H bond functionalization of phenolderivatives with sec/tert-alkyl bromides is reported. Mechanistic studies indicated that the m-CAr–H bond alkylation may involve a radical process and that a six-membered ruthenacycle complex was the active catalyst. Moreover, this approach can provide an expedited strategy for the
