Rhodium(iii)-catalyzed C-H/C-C activation sequence: Vinylcyclopropanes as versatile synthons in direct C-H allylation reactions

Article abstract of DOI:10.1039/c4cc07839j

Succession of C-H activation and C-C activation 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 β-carbon elimination is involved, which represents a novel ring opening mode of vinylcyclopropanes.
