Synthesis and Spectral Properties of N-Aryl-5-hydroxy-1,4-naphthoquinone 4-Imines
摘要:
1,5-Dihydroxynaphthalene, 2,6-dibromo-1,5-dihydroxynaphthalene, and 2,4,6,8-tetrabromo-1,5-dihydroxyraphthalene react with aromatic an-tines in the presence of an oxidant to afford the corresponding N-aryl-5-hydroxy-1,4-naphthoquinone 4-imines.
