Preparation and characterization of two triphenylphosphineiron carbonyl complexes: X-ray crystallographic studies of (1–4-η-5-exo-benzylcyclopenta-1,3-diene)dicarbonyl(triphenylphosphine)iron(0), (1), and dicarbonyl(η-cyclopentadienyl)(triphenylphosphine)iron(II) 1,1,2,3,3-pentacyanopropenide, (2)
The complex [Fe(CH2Ph)(η-C5H5)(CO)2] undergoes a photochemical reaction with PPh3 to yield (1), which has been treated with tetracyanoethylene to yield (2). The products (1) and (2) have been identified and characterized by X-ray crystallography.
