- PHOTOCHEMICAL REACTION OF 9,10-ANTHRAQUINONE AND ITS DERIVATIVES WITH PYRIDINE
-
The previously unknown photochemical reaction of 9,10-anthraquinone with pyridine in an atmosphere of argon takes place with formation of 2-(1,2-dihydropyridino)- or 2-(1,4-dihydropyridino)-9,10-anthraquinone, which is converted by the action of alkali into 2-aminoanthraquinone.In the presence of atmospheric oxygen the reaction product after treatment whith alkali is 1-aminoanthraquinone in addition to 2-aminoanthraquinone.The 1- and 2-methoxyanthraquinones and chloroanthraquinones react with pyridine in the light and form, after treatment with alkali, substituted aminoanthraquinones.
