Abstract
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.Keywords
