Rhodium‐Catalyzed Alkenyl C−H Activation and Oxidative Coupling with Allylic Alcohols

Abstract [Cp*RhCl2]2 was demonstrated to catalyze the oxidative coupling of alkenylpyridines with allylic alcohols through alkenyl C−H activation in the presence of AgOTf and AgOAc to afford β‐alkenyl ketones and aldehydes in moderate to good yields. Allylic alcohol, 1‐aryl and 1‐alkyl allylic alcohols can be coupled with various alkenylpyridines. The reaction occurred at the γ‐position of allylic alcohols and the cis‐β‐position of the alkenylpyridines.
