Cp*Rh(III)-catalyzed regioselectiveC−Hannulation and alkenylation of 2-pyridones with terminalalkynes have been developed. The cationic Cp*Rh(III) catalytic system containing FeCl3 additive enables annulation of 1-(2-pyridyl)-2-pyridones with terminalalkynes, providing efficient access to 5,7-diarylated 2-quinolinones. The reaction pathway can be switched to alkenylation with [Cp*RhCl2]2 as the
