3.4.13 electrophilic substitution of benzene (HL) sear reactions
substrates:
- benzene and activated benzenes
- NO EWGs
pattern:
- activation of electrophile with a Lewis acid
- attack of the “activated” electrophile by the aromatic ring
- deprotonation to restore aromaticity
beware rearrangements: hydride shift alkyl shift
e.g. propyl
mechanism later is same…
attack, deprotonate to restore aromaticity
