Process for the preparation of halogen containing 4-amino phenols

Production of 4-aminophenol derivatives (I) comprises converting an aniline (II) to a diazonium salt (III), reacting (III) with a phenol (IV) in the presence of a base to give a phenylazophenol (V), and reacting (V) with a reducing agent and optionally O-alkylating the product. Production of 4-aminophenol derivatives of formula (I) comprises converting an aniline of formula (II) to a diazonium salt of formula (III), reacting (III) with a phenol of formula (IV) in the presence of a base to give a phenylazophenol of formula (V), and reacting (V) with a reducing agent and optionally O-alkylating the product: [Image] m : 0-3; n : 1-4; m+n : 4 or less; R 1>H, 1-12C alkyl or 5-15C aralkyl; R 2>1-12C fluoroalkyl, 1-12C fluoroalkylthio or 1-12C fluoroalkoxy; Hal : Br, Cl or F; R 3>halo, CN, SCN, SO 3M, NO 2, 1-12C alkyl, 1-12C fluoroalkyl, 1-12C fluoroalkylthio,1-12C fluoroalkoxy, 1-12C alkoxy, 1-12C alkoxycarbonyl, di(1-12C alkyl)amino, 4-14C aryl or 5-15C aralkyl; M : H or alkali metal; p : 0-3; An : an anion.
