- 中文摘要: The intermediates of nitrene-extrusion reaction were found in the forms of (ANB)Fe(CO)/sub 4/ or (ANB)Fe(CO)/sub 3/ during the reaction of 7-azanorbornadiene derivatives (ANB) with diiron nonacarbonyl. By using extended Huckel molecular orbital (EHMO ) calculation, we found that the chemical behavior of these complexes is correlated with the nature of substituents of ANB. The relative reactivity of (ANB)Fe(CO)/sub 4/ and (ANB)Fe(CO)/sub 3/ is influenced by the charge distributions on iron and nitrogen. In the crystal structure of (ANB)Fe(CO)/sub 4/ an angular distortion of Fe-C=O is observed, which is a result of donor-acceptor interaction between the lone- pair of N and the .pi.* orbital of CO.
