The aromatic substitution reactions and mechanisms in organic chemistry form the foundation of benzene ring modifications. Key processes include electrophilic aromatic substitution and Friedel-Crafts reactions.
• Elektrophile Substitution reactions involve the replacement of a hydrogen atom with an electrophile in aromatic compounds
• The mechanism generally proceeds through π-complex and σ-complex formation
• Friedel-Crafts reaction types include both alkylation and acylation, using aluminum chloride as a catalyst
• Directing effects and electronic factors influence the position and rate of substitution
• Various substitution patterns can be achieved through different reaction conditions (KKK rule vs. SSS rule)
