A redox-neutral avenue to access isoquinolines has been realized by a Co(Ⅲ)-catalyzed C-H activation process. Starting from readily available N -sulfinyl imine substrates and alkynes, the reaction occurred via N-S cleavage with broad substrate scope and functional group compatibility in the presence of cost-effective cobalt catalysts.
The rhodium-catalyzed oxidative coupling of aromatic imines with alkynes effectively proceeds viaregioselective C-H bond cleavage to produce indenone imine and isoquinoline derivatives.

An unprecedented C-H functionalization of aryldiazo compounds without a preinstallation of directing group has been realized under mild conditions, which differs from former reports in its use of diazo compounds as coupling partners in directed C-H activations. This novel transformation has been realized by a rhodium self-relay catalysis, a tandem process of the in situ formation of a directing group and sequential C-H bond activation.
