Very stable complexes of general formula [FeCp(CO)xPh2P(Me2Pz)]BF4, where x=1(1)-2(2) were prepared by room temperature reaction of the 3,5-dimethylpyrazolylphosphine ligand with [Fe2 (CO)2(C5H5)2]. When [FeCp(CO)2Ph2P(Me2Pz)]BF4 (1) was treated with (CH3)3 NO·2H2O, one coordinated CO was lost and complex 2 was formed. 1H-, 13C- and 31P-NMR spectra supported a structure of 2 with pyrazolyl ligand chelated to iron forming a four-membered metallocycle. © 2003 Elsevier Science B.V.
