Copper‐Catalyzed C─N Cross‐Coupling of Benzohydrazides with Boronic Acids for N ‐Aryl Amide Synthesis
An operationally simple and efficient protocol for the synthesis of N ‐aryl amides has been developed, based on the copper‐catalyzed coupling of benzohydrazides with boronic acids. The transformation relies on the unique in situ activation of the benzohydrazide precursors using a telescoped mixture of tert ‐but...
