| titleOfInvention | Preparation of perylene-3,4-dicarboxylic anhydrides |
| abstract | Preparation of perylene-3,4-dicarboxylic anhydrides of formula (I) in which R?1, R2, R3, R4, R5, R6, R7, R8¿ are hydrogen, or one radical to eight radicals are a radical selected from the group consisting of an unsubstituted or substituted carbocyclic aromatic radical, an unsubstituted or substituted heterocyclic aromatic radical, halogen, unsubstituted or substituted C¿1?-C18alkyl, -OR?9¿, CN, -NR?10R11, -COR12, -NR13COR12, -NR9COOR12, -NR9CONR10R11¿, -NHSO¿2?R?12, -SO¿2R?12, -SOR12, -SO¿2OR?12, -CONR10R11, -SO¿2NR?10R11, -N=NR14, -OCOR12¿ and -OCONHR12, where each two adjacent radicals together can form a carbocyclic or heterocyclic ring; where R12 is C1-C18alkyl, C6-C10aryl or benzyl which is unsubstituted or substituted by halogen, C1-C4alkyl or C1-C4alkoxy or is a five- to seven-membered heterocyclic radical, R?10 and R11¿ independently of one another are hydrogen, C¿1?-C18alkyl, C3-C24cycloalkyl, C6-C10-aryl, each of which is unsubstituted or substituted by cyano or hydroxyl groups or 5- to 7-membered heteroaryl, or in which R?10 and R11¿ together with at least one of the other radicals R1 to R8 form a 5- or 6-membered carbocyclic or heterocyclic ring; R9 is hydrogen, C¿1?-C18alkyl, C3-C24cycloalkyl, C6-C10aryl or 5- to 7-membered heteroaryl, R?13¿ is hydrogen, C¿1?-C18alkyl, C3-C24cycloalkyl, C1-C4alkylaryl, each of which is unsubstituted or substituted by cyano, hydroxyl or C1-C4alkoxycarbonyl groups, C6-C10aryl which is unsubstituted or substituted by halogen, C1-C4alkyl or C1-C4alkoxy groups, or is a 5- to 7-membered heterocycle, and R?14¿ is the radical of a coupling component or C¿6?-C10aryl which is unsubstituted or substituted by halogen, C1-C4alkyl or C1-C4alkoxy groups by reacting perylene-3,4:9,10-tetracarboxylic anhydride of formula (II) in which R?1 to R8¿ are defined as indicated above, with a sterically hindered amine as a base at elevated temperature, processes for the preparation of further perylene derivatives, perylene derivatives and their use. |
