Copper-catalyzed C-N coupling reaction of tosylhydrazones

Tosylhydrazones are a kind of labile and highly reactive compounds, which are apt to be transformed into reactive diazo compounds and then into extremely reactive carbenes under the basic condition. In order to fulfil the valuable C-N coupling reaction, diaryliodonium salts are evaluated and prove to be a class of efficient electrophiles. The reaction with ligand-free copper salt as catalyst shows a wide range of substrate scope. A plausible mechanism is proposed.

N-ARENESULFONYL-N-PHENYLHYDRAZONES

The phenylhydrazones of aliphatic aldehydes and ketones, and those of benzaldehyde and benzophenone react with various sulfonylchlorides in the presence of a suitable base to give the title compounds; examples of their synthetic use are given.
