Abstract

1416603 Dyestuffs HOECHST AG 24 April 1973 [26 April 1972 31 July 1972 (4) 14 Aug 1972 (2) 30 Aug 1972 (3) 21 Sept 1972 (3)] 19298/73 Heading C4P [Also in Division G2] The compound of formula (4,5 - dichloronaphthoylene benzimidazole) is made by condensing o-phenylene diamine and 4,5-dichloronaphthalic acid anhydride. A quinonyl diazo naphthylene derivative of formula is made by forming a diazonium salt from 6- amino-4,5,8-trimethyl-2-hydroxy quinoline and. coupling it with 5-(2<SP>1</SP>,3<SP>1</SP>-hydroxynaphthoylamino)benzimidazolone. The compound of formula can be made in an analogous manner. A trisazo derivative of formula is made by forming a diazonium salt of 4,4<SP>1</SP>- diamino - 2,2<SP>1</SP> - dichloro - 5,51 - dimethoxyazobenzene and coupling it with 1-phenyl-3- methyl pyrazolone. Compounds wherein the phenylene nuclei may be substituted by a methyl group or two chloro or methoxy groups may be made in an analogous way. The benzoxanthene derivative of formula is made by the reaction of 10-methoxy benzoxanthene 3,4-dicarboxylic acid anhydride with 3- aminopyrene. A trisazo derivative of formula wherein R 9 and R 10 are methoxy and R 11 and R 12 are chloro, is afforded by coupling the diazonium salt of 4,4<SP>1</SP>-diamino-2,5<SP>1</SP>-dichloro-5,2<SP>1</SP>- dimethoxy azobenzene with acetoacetanilide. The compound wherein R 9 and R 11 are chloro, R 10 is methoxy and R 12 is methyl, can be made in a similar way. A diazomethine of formula is formed by the reaction of 4,41-diaminodiphenyl ether or with dimethylamino benzaldehyde in dimethyformamide. The perylene derivative of formula where R is pyenyl is made in Example 13 by heating perylene-3,4,9,10-tetracarboxylic acid and 3-amino-pyrene in a mixture of quinoline and concentrated sulphuric acid. Dioxatetra-aza-pentacenes of formula wherein R 1 is H are formed in Example 46 from 1,4 - dihydroxy - cyclohexa - ,1,4 - diene - 2,5- dicarboxylic acid ethyl ester and 2-aminopyridine to give tetrahydro compounds of formula which are subsequently boiled under reflux in a mixture of nitrobenzene, glacial acetic acid and piperidine to yield the pentacene.
