Ullmann Condensation Reaction of Haloanthraquinone Derivatives with Amines in Aprotic Solvents

Cuprous catalysts were more effective than cupric ones in the Ullmann condensation of haloanthraquinones with amines in aprotic media. In the presence of Cu(I) catalyst, amines with a hydroxyl group (3-amino-1-propanol and 2-aminoethanol) were more reactive than the higher basic butylamine.
