Abstract
THE results obtained recently by Farenhorst and Kooyman1 on the relative reactivities of substituted anthracenes towards radical attack lend support to the validity of the simple molecular orbital theory of radical reactions. The results show (Table 1) that substitution at the 9-position enhances the activity towards radical attack at the 10-position irrespective of the polarity of the substituent group.
