Qualitative estimation was made of the direction of the cleavage of ether-linked oxygen in 1-phenoxynaphthalene (I), 2-phenoxynaphthalene (II), 1, 1′-dinaphthyl ether (III), 1, 2′-dinaphthyl ether (IV) and 2, 2′-dinaphthyl ether (V) by the application of metallic sodium in liquid ammonia. As a result, (I) and (II) were both cleaved to phenol and naphthalene, or benzene and naphthol, but such cleavage did not proceed with (III), (IV) and (V), majority of these reaction products forming resinous substances.
