The radical coupling mechanism in the diazo coupling reaction. Migration vs. decomposition of phenylazo radical generated from phenylazo 1-naphthyl ether in the solvent cage
The thermal reaction of phenylazo 1-naphthyl ether generates a pair of phenylazo and naphthoxy radicals in the solvent cage, in which these radicals couple together at the aromatic carbon to give 4-phenylazo-1-naphthol and 2-phenylazo-1-naphthol.

The reaction of benzenediazonium ion generated from α-azohydroperoxide with 1-naphthol gave a diazoether which rearranged to 2- and 4-phenylazo-1-naphthols.

The base and acid catalyzed reactions of phenylazo 1-naphthyl ether () yielded biphenyl () and 1-naphthol () as major products accompanied with 4-phenylazo- () and 2-phenylazo-1-naphthols (). All of our observations do not support the Kekulé's diazo coupling mechanism.
