A Preliminary Study on Chemistry of Phenoxynaphthacenequinones

A preliminary study on the chemistry of 6-phenoxy-5.12-naphthacenequinone derivatives was reported. It was found that the main product was 6-(N,N-dimethylamino)-5,12-naphthacenequinone when a reaction of 6-chloro-5,12-naphthacenequinone with 4-hydroxyazobenzenes in DMF was carried out under certain reaction conditions. When the reaction of 6-E4-(4-hydroxyphenyl)isopropyl)phenoxy]-5,12-naphthacenequinone and epichlorohydrin was carried out in an acetone/DMF(V/V=2/1) mixed solvent and in the presence of K 2 CO 3 and KI, a new phenoxynaphthacenequinone derivative,6,6′-[1-methylethylidenebis(4,1-phenyleneoxy)]bis(5,12-naphthacenequinone), was obtained.
