Perylene-3,4-dicarboximides 2 are obtained by a decarboxylizing condensation of moderately sterically hindered primary amines with perylene-3,4,9,10-tetracarboxylic 3,4:9,10-bisanhydride (3) in the presence of water.Perylene-3,4-dicarboxylic anhydride (4) is prepared by hydrolysis of the imides with KOH in tert-butyl alcohol.The anhydride may be condensed with any primary amine to the corresponding imide.The imides are highly fluorescent and very photostable dyes. - Key Words: Fluorescent dyes/Pigments/Perylenes/Carboximides
