摘      要：正Diaryl carbazone is an important organic analytical reagent normally prepared by the oxidation of diaryl carbazine, but in literatures’ methods, the yields were low and the procedures were trouble. Recently, our laboratory reported some new methods for the preparation of diaryl carbazone from diaryl carbazine. Generally, these reactions were carried out in solution and have drawbacks such as tedious operation;using large amounts of volatile and poisonous solvent which will pollute the environment inevitably;complicated oxidation system.
