Minimizing risk: The synthesis of arylhydrazines through C?￡?N cross-coupling of aryl chlorides with hydrazine is described. Through the use of continuous flow, the hazards associated with the use of hydrazine in the presence of transition metals are decreased. In addition, multistep flow sequences have also been developed for the generation of functionalized heterocycles utilizing the arylhydrazine intermediates.

Hydrazine is not a problem anymore: The title transformation is the first reaction to yield aryl hydrazines through the cross-coupling of aryl chlorides and tosylates with hydrazine. An appropriately designed palladium catalyst allows this reaction to proceed rapidly under mild conditions, and with excellent chemoselectivity (see scheme; Ad=adamantyl, Ts=4-toluenesulfonyl).
