摘要:
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). © 2010 WILEY-VCH Verlag GmbH & Co.
