WHEN certain phenyl ethers are heated at their boiling points, the non-aromatic group migrates from the oxygen to the nucleus. The more important groups which so migrate are allyl, benzyl and tert.alkyl. If the rearrangement of some of these ethers is effected in a suitable solvent, the migrating group is transferred, in part, to the solvent. Thus by heating a quinoline solution of benzylphenyl ether, benzyl quinoline is formed together With the normal products of the rearrangement. Toluene is also formed.
