摘要:
A process for preparing quaterrylene-3,4:13,14-tetracarboximides of the general formula I in which R, R′ are each independently hydrogen or optionally substituted C1-C30-alkyl, C5-C8-cycloalkyl or aryl or hetaryl; which comprises reacting a perylene-3,4-dicarboximide of the general formula IIa in the presence of a base-stable, high-boiling, organic solvent and of an alkali metal base or alkaline earth metal base, with a perylene-3,4-dicarboximide of the general formula IIb in which X is hydrogen, bromine or chlorine.
