Oxidation of 1,5-dihydroxy-, 2,6-dibromo-1,5-dihydroxy-, and 2,4,6,8-tetrabromo-1,5-dihydroxy-naphthalenes with Ag2O or PbO2 in the presence of butylamine or methylamine leads to formation of the corresponding 4-alkylamino-and 2,4-bis(alkylamino)-1,5-naphthoquinone which exist in organic solvents as tautomeric mixtures with N-alkyl-5-hydroxy-1,4-naphthoquinone 4-imines.
