Electrophilic substitution
The alkoxy group (-OR) is ortho, para directing and activates the
aromatic ring towards electrophilic substitution in the same way as
in phenol (i) Halogenation: Phenylalkyl ethers undergo usual halogenation
in the benzene ring, e g , anisole undergoes bromination with
bromine in ethanoic acid even in the absence of iron (III) bromide
catalyst
