A Transition-Metal-Free Synthesis of Arylcarboxyamides from Aryl Diazonium Salts and Isocyanides
摘要:
A transition-metal-free carboxyamidation process, using aryl diazonium tetrafluoroborates and isocyanides under mild conditions, has been developed. This novel conversion was initiated by a base and solvent induced aryl radical, followed by radical addition to isocyanide and single electron transfer (SET) oxidation, affording the corresponding arylcarboxyamide upon hydration of the nitrilium intermediate.

The copper-catalyzed cross-coupling reaction of aryl diazoniumsalts and isocyanides has been performed. This is a successful example of preparation of arylcarboxyamides with moderate to good yield under mild conditions.
