    Notes: Summary Coupling reactions of the diazoniumbetaines2, 4, 6a, 6b, 6c with derivatives of 1,6-methano[10]annulene1a–c and/or β-naphthol7 yield the dyes3a–c, 5a, 5c, 8a–c, 9, 11. The syntheses of different triazine derivatives12a–c, 13a–c, 15, 16, and17a, 17c are described.

    Synthesen neuer Azofarbstoffe mit 1,6-Methano[10]annulen-Partialstruktur (1991)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 124 (1991), S. 537-542 
    Details
    ISSN: 0009-2940
    Keywords: 1,6-Methano[10]annulene ; Quinones, bridged ; Acylations ; Azo dyes ; Chemistry ; Inorganic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: Synthesis of New Azo Dyes with 1,6-Methano[10]annulene Partial StructureBridged quinone hydrazones 1 are transformed by aromatic acyl chlorides to the corresponding azo dyes 3a -6. Nitro derivative 1a reacts analogously with p-tolylsulfonyl chloride, acetyl chloride, methyl chlorocarbonate, and dimethylcarbamoyl chloride to give the corresponding azo dyes 7 and 8a -c. Reaction of 1a with diphenylcarbamoyl chloride unexpectedly leads to Berson-Wilcott rearrangement with formation of the azo dye 9. Acylations of 1a with the bifunctional acyl chlorides diphosgene and terephthaloyl chloride yield the azo derivatives 11 and 12.
