Title:
PRODUCTION OF PERYLENE-3,4,9,10-TETRACARBOXYLIC ARYLIMIDE
Document Type and Number:
Japanese Patent JPS61238853
Kind Code:
A
Abstract:
Process for the preparation of compounds of the formula (1) (1) in which R1 denotes a phenyl or naphthyl radical which can be substituted by alkyl, cycloalkyl, alkoxy, aryloxy, arylazo or nitro groups or halogen atoms, and R2 denotes a hydrogen atom or a phenyl or naphthyl radical which can be substituted by alkyl, cycloalkyl, alkoxy, aryloxy, arylazo or nitro groups or halogen atoms, or denotes an alkyl (C1-C8) radical, by condensation, at between 100 DEG C. and 300 DEG C., of perylene-3,4,9,10-tetracarboxylic dianhydride or a monoanhydride monoimide of the formula (2) (2) in which R2 has the abovementioned meaning, with an arylamine of the formula (3) R1-NH2 (3) in which R1 has the abovementioned meaning, in the presence of dialkylamines of the formula (4) (4) in which R' and R'' denote straight-chain alkyl C1- C6 or branched alkyl C3-C6 or cycloalkyl C5-C6 groups, which can be substituted by hydroxyl, alkoxy C1-C4, alkyl C1-C4 amino, or phenyl or naphthyl groups which can be substituted on the aromatic nucleus by alkyl C1-C4, alkoxy C1-C4 or alkyl C1-C4-amino groups or halogen atoms, and in which R' and R'' can form with the nitrogen atom a 5- or 6-membered heterocyclic ring.
