Chemical compound

(Triphenylphosphine)iron tetracarbonyl is a coordination complex with the formula Fe(CO)4(PPh3) (Ph = C6H5). An off-white solid, this complex is derived from iron pentacarbonyl by replacement of one carbonyl ligand by triphenylphosphine (PPh3).

## Synthesis and use

[edit]

The title complex can be prepared by reaction of iron pentacarbonyl or triiron dodecacarbonyl with triphenylphosphine:[1]

Fe3(CO)12 \+ 3 P(C6H5)3 → 3 Fe(CO)4(P(C6H5)3)

The substitution is catalyzed by cobalt chloride.[2]

(Triphenylphosphine)iron tetracarbonyl is an intermediate in the synthesis of bis(triphenylphosphine)iron tricarbonyl. Both the mono- and bis(triphenylphosphine) complexes were originally employed in pioneering research on homogeneous catalysis by Walter Reppe.[3]
