The compounds cpFe(C0)2H and HMn(C0)5 (cp = cyclopentadienyl) react with 1,3-dienes to give the 2-enylmetal products of 1,4-addition of the metal hydrides to the dienes; CIDNP studies indicate that the process involves a radical pair mechanism.

Staffordshire ST5 5BGMethods for the resolution of tricarbonyl( 1 -5-q-cyclohexadienyl) iron salts are described involving the separation of diastereoisomeric pairs obtained by nucleophilic attack using chiral phosphines, alkoxides, and amines. Nucleophilic attack by CN-on [Fe(q5-C,H,) (CO)2L'J BF4 to give [Fe(C6H7CN-exo-5) (CO),L*] [L' = (+)-neomenthyldiphenylphosphine] proceeds with significant asymmetric induction at the chiral carbon so formed.
