- 中文摘要: The reaction of stoichiometric MeLi with the 1:1 mixture of (h5-C5H5)Fe(CO)2I/P(OR)3 (R = Me, Et, and Ph) at -78 ?/fontC changes the bonding mode between metal and ring from (h5-C5H5) to (h4-exo-MeC5H5) and the oxidation state of metal from Fe(II) to Fe(0), the novel complexes (h4-exo-MeC5H5)Fe(CO)2P(OR)3 being obtained in 45-57% yields. The reaction of trace MeLi with the 1:1 mixture of (h5-C5H5)Fe(CO)2I/P(Ome)3 at -78 ?/fontC results in 70% yield of the phosphonate complex (h5-C5H5)Fe(CO)2P(O)(Ome)2 which is an Arbuzov-like dealkylation product from the cationic intermediate [(h5-C5H5)Fe(CO)2P(Ome)3+] and the iodide. The amines could assist the Arbuzov-like dealkylation of [(h5-C5H5)Fe(CO)2P(Ome)3+][PF6-] where iron-carbamoyl intermediates are likely involved in the case of primary amines.
