Insertions of allenes into iron-acyl bonds proceed readily and quite efficiently.When the reaction product is neutral an η3-allyl ligand is generated, but not when the product is an anion.Transfer of electronic density to the organic ligand is shown to occur.This is reflected in ion pairing phenomena which are studied by monitoring the change in ν(CO) and ν(C=O) in the IR as a function of the solvent and/or the counter ion.The oxygen of the ligand oxo group is the site of interaction with the cation Na+.
