Synthesis, structure and reactions of a carbon dioxide complex of iron(0) containing 1,2-bis(diethylphosphino)ethane ligands

Abstract

Reaction of [Fe(N2)(depe)2] with carbon dioxide gives trigonal bipyramidal [Fe(η2-CO2)(depe)2], where the coordinated CO2 lies on equatorial plane by an η2-fashion and converts into dimethyl ether and [FeX(CO)(depe)2]X (X = I, OTf) on interaction with methyl halide or triflate.
