    Abstract: A process for preparing terylene-3,4:11,12-tetracarboximides I where the variables are each defined as follows: R, R' are each independently hydrogen; if desired substituted alkyl or cycloalkyl; R 1 is hydrogen or alkyl; R 2 is hydrogen; alkyl; if desired substituted aryl or hetaryl, by reacting a perylene-3,4-dicarboximide II in the presence of a base-stable, high-boiling organic solvent and of an alkali metal or alkaline earth metal base, with a naphthalene-1,8-dicarboximide III in which X is hydrogen, bromine or chlorine.

    Abstract: The invention concerns a process for producing and purifying perylene-3,4-dicarboxylic acid imides by reaction of a perylene-3,4,9,10-tetracarboxylic acid or corresponding anhydrides using a primary amine: reaction is carried out in the presence of a tertiary nitrogen base compound as the solvent and a transition metal or transition metal salt as the catalyst. The invention further concerns the purification of perylene-3,4-dicarboxylic acid imides obtained by reaction of a perylene-3,4,9,10-tetracarboxylic acid or corresponding anhydrides using a primary amine: the raw products are first heated in N-methyl pyrrolidone, the N-methyl pyrrolidone adducts thus produced are treated with a base in the presence of an organic diluting agent, and the products subsequently isolated undergo further treatment if necessary with an aqueous acid. The invention also concerns novel perylene-3,4-dicarboxylic acid imides and the use thereof as fluorescence dyes, pigments or pigment additive precursors.
