Palladium catalyzed Buchwald-Hartwig reactions between aryl halides and N-nucleophiles, and the copper catalyzed Chan-Evans-Lam reactions between aryl boronic acids and N-nucleophiles are all effective methods for constructing C-N bonds. Herein, under palladium acetate/tert-butanol system or copper acetate/dichloromethane system, benzophenone hydrazone can react with aryl chlorides and aryl boronic acids to afford corresponding aryl hydrazones, respectively. The obtained products are easily hydrolyzed to form aryl hydrazines, thus providing an indirect pathway to access aryl hydrazines from relatively less toxic reagents.

Key words: Buchwald-Hartwig reaction, Chan-Evans-Lam reaction, aryl boronic acid, benzophenone hydrazone
