Abstract
The nucleophilic cleavage of differently activated aryl ethers by a fluoride anion is studied. Two sulphone groups in para positions to the ether link appear to activate this sufficiently to allow its nucleophilic substitution by F- to occur from 280-degrees-C upwards. No reaction is observed up to 300-degrees-C when two ketone links are para to the ether, whilst the reaction occurs from 300-degrees-C upwards in the case of a mixed sulphone-ketone activation.
