The reaction of Cp(CO)2Fe-EMe2 (E=As,Sb,Bi) with Me3P, Et3P, Me2PhP and (MeO)3P leads to a CO/R3P exchange and formation of the chiral derivatives Cp(CO)(R3P)Fe-EMe2.Cp(CO)<(MeO)3P>Fe-EMe2 rearranges already at room temperature to Cp(CO)Fe-P(O)(OMe)2.The high nucleophilicity of the new organometallic Lewis bases is established by the easy conversion of Cp(CO)(Me3P)Fe-SbMe2 to I with MeI, or to Hal (L = CO, Hal = Cl; L=Me3P, Hal = Br) with Cp(CO)LFe-Hal, respectively.The new compounds are characterized by spectroscopy and elementary analyses.
