PROBLEM TO BE SOLVED: To provide a method for producing phenylhydrazines capable of substantially removing unnecessary metal salts after reaction in a method for producing phenylhydrazines by reducing a diazonium salt using a metal salt reducing agent. In a method for producing a phenylhydrazine represented by a general formula (2) by reducing a diazonium salt represented by a general formula (1) using a metal salt reducing agent, unnecessary after completion of the reaction. A method for producing a phenylhydrazine represented by the general formula (2), characterized in that a simple metal salt is substantially removed with a chelating agent. [Chemical 1] Formula (1) and general formula (2), R 1 represents a substituent, n is an integer of 0-5. When n is 2 or more, R 1 may be the same or different, and may be connected to each other to form a ring. In the general formula (1), X − represents an anion. [Selection figure] None |
