Abstract
The invention involves a procedure for synthesizing aryl hydrazine through reduction of a diazo derivative. The distinguishing feature of the method is that it involves at least the following step: c) bringing a diazo derivative into contact with a sulphite solution in which the pH level is at least 7. Applications: organic synthesis.
