The alkenylation reactions of 8-methylquinolines with alkynes, catalyzed by [{Cp*RhCl2}(2)], proceeds efficiently to give 8-allylquinolines in good yields by C(sp(3)) H bond activation. These reactions are highly regio- and stereoselective. A catalytically competent five-membered rhodacycle has been structurally characterized, thus revealing a key intermediate in the catalytic cycle.
