The synthesis and room temperature single-crystal X-ray structural characterization of the title compound [(PhCH=CHCH=NCHMePh)Fe(CO)2(PPh3)] are described, the first optically pure 1-azabuta-1,3-diene adduct of iron(0) to be so recorded. Crystals are orthorhombic, P 212121, a 20.197(6), b 14.09(1), c 11.094(5) ?, Z 4; conventional R on |F| was 0.061 for 2217 independent 'observed' (I > 3σ(I)) reflections. This compound has been employed to transfer the Fe(CO)2(PPh3) moiety to cyclic 1,3-dienes to give new complexes, including the first example of optically active dicarbonyl(triphenylphosphine) (η4-1-methoxycyclohexa-1,3-diene)iron.

A preparative method for novel polymer-supported Fe(η5-dienyl)(CO)2(PPh2-polystyrene) species from [Fe(η5-dienyl)(CO)3]+ (dienyl = C6H7, 2-MeOC6H6 or C7H9) cations has been developed. The polymer-supported complexes have been characterised by iron analysis and infrared and 31P NMR spectroscopic studies and shown to undergo nucleophilic attack on the dienyl ring in a similar fashion to that of their monomeric analogues. Treatment of the resultant adducts with trifluoroacetic acid regenerated the starting dienyliron polymers.
