Succession of C-Hactivation and C-Cactivation was achieved by using a single rhodium(III) catalyst. Vinylcyclopropanes were used as versatile coupling partners. Mechanistic studies suggest that the olefin insertion step is rate-determining and a facile beta-carbon elimination is involved, which represents a novel ring opening mode of vinylcyclopropanes.
