The reaction of tertiary phosphines, PR3, with six- and seven-membered ring dienyl complexes of Fe(CO)3 produces the corresponding phosphoniodiene salts.These salts undergo deprotonation on treatment with either LinBu or NaH and undergo a subsequent reaction with aldehydes (R'CHO) to yield the appropriate olefinic complexes.With , reaction with Ph3 produces simple substitution complexes of the type .Treatment of with HPF6 produces a salt of unknown structure which reacts with PPh3 to produce tricarbonyl(triphenylphosphoniomethylcyclo-octatetraene)iron hexafluorophosphate.Reaction of this salt with LinBu and HCHO yields tricarbonyl(vinylcyclo-octatetraene)iron.
