The structure of [(Me2As)(5=CCF F2(AsMe2)Fe3(CO)g] has been reported.Treatment of the mono-olefin chelate [Fe(CO)3(sp)], (sp = o-CH2=CHCgH PPh2) with HX (X = Cl or Br) in hexane gives the Fe complex (34), whose structure has been assigned on the basis of an X-ray study on the Ru—Br analogue. The iron compounds appear to be the first octahedral a-bonded alkyls of Fe .  

The reactions of a number of iron carbonyl compounds with [(PhPCH2-CH2]2PPh (Pf.PfiPf) are summarized in Table 2. Fe(CO) l2 reacts with the 

These compounds react with anhydrous HX (X = Cl or Br) to yield the halogenated-fluorophosphine complexes e.g
