| Abstract: | Reactions of 2-(4-hydroxyarylamino)-1,4-naphthoquinones with cerium ammonium nitrate or pyridinium chlorochromate depending
on the structure of initial substrate and the type of reagent led to the formation of 2-chloro-3-(4-cyclohexa-2,5-dienylideneamino)-1,4-dihydronaphthalene-1,4-diones,
2-(4-hydroxy-3-nitrophenylamino)-1,4-naphthaquinones, and also to simultaneous oxidation and chlorination. |
