Both the regioselectivity—the diverse arene substitution patterns—and the speed of an electrophilic aromatic substitution are affected by the substituents already attached to the benzene ring. In terms of regioselectivity, some groups promote substitution at the ortho or para positions, whereas other groups favor substitution at the meta position. These groups are called either ortho–para directing or m… WebIllustrated Glossary of Organic Chemistry - Electrophilic aromatic substitution (EAS) Illustrated Glossary of Organic Chemistry. involves attack of the by an electrophile. …
