Synthesis and spectral properties of N-aryl-5-hydroxy-1,4-naphthoquinone 4-imines

1,5-Dihydroxynaphthalene, 2,6-dibromo-1,5-dihydroxynaphthalene, and 2,4,6,8-tetrabromo-1,5-dihydroxynaphthalene react with aromatic amines in the presence of an oxidant to afford the corresponding N-aryl-5-hydroxy-1,4- naphthoquinone 4-imines.

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
