Abstract

We have developed a Rh(III)-catalyzed C–H alkenylation reaction of the N,N-bidentate chelating compound 2-(1H-pyrazol-1-yl)pyridine with alkenes via rollover cyclometalation. Mono- and dialkenyl-substituted 2-(1H-pyrazol-1-yl)pyridines could be selectively synthesized in moderate to good yields by tuning the reaction conditions. Further synthetic transformations were conducted to demonstrate the synthetic potential of our products.
