Bromination as Electrophilic Aromatic Substitution

The source introduces bromination of benzene as following the general mechanism for electrophilic aromatic substitution.

C6H6+Br2→FeBr3C6H5Br+HBrC_6H_6+Br_2\xrightarrow{FeBr_3}C_6H_5Br+HBr
electrophilic aromatic substitution
benzeneE+E+ H+attackaromaticity is restored after proton loss

Notes

  • Bromine itself is not sufficiently electrophilic to react with benzene.

  • FeBr3FeBr_3 acts as the Lewis acid catalyst.
