PURPOSE:To provide the subject compound useful for agricultural chemicals, drugs, decomposable polymers, various recording material, etc. CONSTITUTION:A compound of the formula (R2-R6, Rx, Ry are H, alkyl, aryl, alkoxy, aryloxy, substituted amino, acyl, halogen, etc.; R5 and R6, R2 and R3 and R4, and Rx and Ry can be combined with each other to form 4-8 membered rings, respectively; the connecting bonds X and Y are divalent organic groups required for forming a 4-15 membered ring), e.g. 11H-benzo [a]carbazole-8-ol-, 5, 6,-dihydro-11-phenylamine. The compound is obtained by reacting a phenol compound having a cyclic unaturated double bond at the m-position with a diazonium salt in a basic atmosphere and subsequently treating the reaction product with an acid. The compound is useful as an image-forming system utilizing the reducing property of the dihydro compound, as a stable radical and radical quencher in the form of the DPPH analogous compound of the anilino-substituted indole derivative, as a carbazole derivative or an intermediate for photoconductors, couplers, etc. |
