Аннотация:The reaction of Cr(CO)(6) with 7,7-dichloro-3,4-benzobicyclo[4.1.0]hep gave the corresponding exo- and endo-chromium tricarbonyl complexes in a ratio of 4.5:1 The structures of the resulting compounds were established by NMR spectroscopy, mass spectrometry, and X-ray structural analysis. Reduction of dichlorobenzobicycloheptane and its chromium tricarbonyl complexes with LiAlH4 afforded exo- and endo-7-chloro-3,4-benzobicyclo[4.1.0]heptanes in a 3.5:1 ratio.
