摘要: Methylenecyclopropanes are important synthetic intermediates that possess strain energies exceeding those of saturated cyclopropanes by> 10 kcal/mol. This report describes a catalytic reductive methylenecyclopropanation reaction of simple olefins, utilizing 1, 1-dichloroalkenes as vinylidene precursors. The reaction is promoted by a dinuclear Ni catalyst, which is proposed to access Ni2 (vinylidenoid) intermediates via C Cl oxidative addition.
