Cationic Co(III)-catalyzed C–H/N–N bond functionalization of arylhydrazones with internal alkynes has been developed for the synthesis of isoquinoline derivatives. The arylhydrazones are easy to prepare and require inexpensive and commercially available hydrazine hydrate. The reaction works well with a variety of internal alkynes and arylhydrazones and offers broad scope, good functional group tolerance
The rhodium-catalyzed oxidative coupling of aromatic imines with alkynes effectively proceeds viaregioselective C-H bond cleavage to produce indenone imine and isoquinoline derivatives.

Abstract An efficient rhodium-catalyzedoxidativecoupling reaction has been developed that gives high yields of multisubstituted isoquinolines from easily accessible aryl hydrazones and internal alkynes. Indenone hydrazone can also be synthesized in high yield from the corresponding benzaldehyde hydrazone by using this approach. An efficient rhodium-catalyzedoxidativecoupling reaction has been developed
