    摘要: The invention relates to a method for producing perylene-3,4-dicarboxylic acid imides, which carry a sterically exacting substituent on the imide nitrogen atom, by reacting a perylene-3,4:9,10-tetracarboxylic acid dianhydride with a sterically hindered primary amine in a reaction medium that is essentially devoid of water. The method is characterised in that the reaction takes place in the presence of a tertiary amine, a cyclic imine- or amide-based solvent and a Lewis acid as the catalyst.
