The Homocoupling of Arylsulfonylhydrazides by Palladium-Catalysed Desulfonation in Air
摘要:
A simple and efficient preparation of biaryl derivatives from arylsulfonyl hydrazides has been developed using Pd(OAc)(2) as the catalyst in a mixed solvent of DMA and THF and without the use of any ligand and base.
denitrogenative and desulfinative addition of arylsulfonyl hydrazides with nitriles has been successfully achieved under mild conditions. This transformation is a new method for the addition reaction to nitriles with arylsulfonyl hydrazides as arylating agent, thus providing an alternative synthesis of aryl ketones. The reported addition reaction is tolerant to many common functional groups, and works
