(57) [Summary] (Modified) [Constitution] General formula (I) The compound of the general formula (II) is characterized by reacting the metal complex of the o-hydroxynitroso aromatic compound represented by A method for producing a metal complex of an o-hydroxynitroso aromatic compound represented by: [In the general formulas (I) and (II), R 1 represents a hydroxy group, an amino group, an alkoxy group, an alkyl group, It represents a substituent selected from a halogeno group, a cyano group and the like. n represents an integer of 0 to 3. X represents a substituent selected from an amino group, an alkoxy group, an alkylthio group and the like. α The ring represents a ring having 3 to 18 carbon atoms, including the case where there is no α ring. [Effect] A metal complex of an o-hydroxynitroso aromatic compound having a wide variety of substituents at the para position of the nitroso group and the meta position of the hydroxy group, which is useful as a synthetic intermediate for functional dyes, can be easily produced. can do. |
