The title complex can be prepared by reaction of triiron dodecacarbonyl with excess triphenylphosphine:[1]
(Triphenylphosphine)iron tetracarbonyl is an intermediate in the synthesis of this compound. The title complex can also be produced more efficiently by borohydride-catalyzed substitution of iron pentacarbonyl.[2][3]
Protonation gives the ferrous hydride:[4]
Both the mono- and bis(triphenylphosphine) complexes were originally described by Walter Reppe.[5]
