  Catalytic Olefin Cyclopropanation Using μ-Oxo−bis[(salen)iron(III)] Complexes

  摘要：

  A series of mu-oxo-bis[(salen)iron(III)] complexes was prepared from the reaction of the corresponding salen ligands with FeCl3.6H(2)O in the presence of NEt3, and characterized by elemental analysis, infrared spectroscopy, and mass spectrometry. These air-stable complexes catalyzed the cyclopropanation of olefins with ethyl diazoacetate in good yields. The catalytic activity of these mu-oxo dimers, in the cyclopropanation of styrene, was examined as a function of the diamine backbone and the substituents in the 3,3'- and 5,5'-positions of the phenyl rings on the ligands. Solvent variation, catalyst loading, and styrene concentration were investigated to determine the optimal reaction conditions. The complex [Fe(3,3',5,5'-Bu-t(4)-salen)](2)O (1d) was identified as the most efficient catalyst in the series, which successfully catalyzed the cyclopropanation not only of styrene but also of less reactive substrates such as alpha-methylstyrene, alpha-(trifluoromethyl)styrene, 1,1-diphenylethylene, methylenecyclohexane, and n-butyl vinyl ether and internal olefins such as trans- and cis-beta-methylstyrene and ethylidenecyclohexane.
