The reaction of 1-amino-4-acylaminoantraquinones with piperidine in the presence of CoCl2 and atmospheric oxygen gave the 2-aminated products in 75-80percent and similar reaction of 1-hydroxyantraquinone or 1-aminoantraquinone-2-sulfonic acid with butylamine gave the corresponding 4-aminated products, respectively.The effects of the α-substituents and the role of metal salts were discussed.
