Advanced Organic Chemistry: Reactions And Mechanisms
But what about benzylic, allylic. vinylic and aryl halides? Let us first consider
benzylic and allylic halides. Benzylic and allylic halides readily undergo ^2
reactions unless they are tertiary. Tertiary benzylic and allylic halides, like other
tertiary ...

Organic Chemistry, Enhanced Edition
Benzyl group Reactions involving alkyl side chains of aromatic compounds occur
preferentially at the benzylic position for two reasons. First, the benzene ring is
especially resistant to reaction with many of the reagents that normally attack ...
