The free radical bromination of aryl methyl groups can be controlled by the strategic positioning of a remote stereo-electroni blocking group on the aryl ring. This tactic leads to the efficient synthesis of selectively benzylically brominated molecules whichare useful synthetic intermediates. This methodology has been applied to the synthesis of some phthalides.
