OXIDATIVE COUPLING OF 1,5-DIHYDROXYNAPHTHALENE WITH AROMATIC AMINES

The oxidative coupling of 1,5-dihydroxynaphthalene with aromatic amines leads to the formation of N-aryl-5-hydroxy-1,4-naphthoquinone-4-imines.The yield of these products depends on the nature of the oxidizing agent.

REACTION OF 1,5-DIHYDROXYNAPHTHALENE WITH AROMATIC AMINES

The action of heat on 1,5-dihydroxynaphthalene in naphthalene or p-toluidine, blown with air, at 100 deg C leads to the formation of a mixture of 5-hydroxy-4-arylimino-1-naphthalenone, 5-hydroxy-2-arylamino-4-arylimino-1-naphthalenone, 1,5-diarylamino-4,8
