Controlling the degree of substitution of iron pentacarbonyl with neutral ligands has usually been difficult. Conditions are reported whereby considerable control may be exercised over the substitution of iron pentacarbonyl; with PPh3 the ratio of mono-/disubstitution may be varied over a range of 50. The substituted iron carbonyl complexes were obtained by treating iron pentacarbonyl with lithium aluminum hydride or sodium borohydride in refluxing THF in the presence of a variety of neutral ligands. The method is particularly useful for a simple high yield synthesis for monosubstituted iron carbonyls.
