A simple new method is decribed for the generation of the (dicarbonyl)(η5-cyclopentadienyl)iron cation (Fp+).This coordinatively unsaturated species forms complexes of the type + with various neutral ligands L (L = olefins, dienes, ketones, aldehydes, esters, nitriles, nitro compounds, acetic acid, tetrahydrofuran, dimethylformamide, dimethylsufoxide, and triphenylphosphine).
THE PREPARATION AND PROPERTIES OF CATIONIC DICARBONYLCYCLOPENTADIENYLIRON COMPLEXES OF ORGANIC CARBONYL COMPOUNDS: MOLECULAR STRUCTURE OF DICARBONYLCYCLOPENTADIENYLIRON(3-METHYLCYCLOHEXENONE) HEXAFLUOROPHOSPHATE

A number of complexes CpFe(CO)2(L) (L = aldehyde, ketone, ester, amide) have been prepared either by treatment of 2 or CpFe(CO)2Br with AgPF6 in the presence of L or by a ligand exchange reaction employing CpFe(CO)2(isobutylene)BF4.NMR spectral data suggest that these complexes involve iron-oxygen ?-bonding rather than ?-bonding to the carbonyl group.This is confirmed by an X-ray structure determination of the 3-methylcyclohexenone complex.The exchange stability of these complexes parallels their basicity.
