                                摘要:
                                A cationic Rh(I)-catalyzed [5 + 1] cycloaddition of vinylcyclopropanes and CO has been developed, affording either beta,gamma-cyclohexenones as major products or alpha,beta-cyclohexenones exclusively, under different reaction conditions.
