Alkenes in (alkene)dicarbonyl(r 5-cyclopentadienyl)iron(l +) cations react with carbon nucleophiles to form new C—C bonds (M. Rosenblum, 1974 A.J. Pearson, 1987). Tricarbon-yl(r 3-cyclohexadienyl)iron(l +) cations, prepared from the T)4-1,3-cyclohexadiene complexes by hydride abstraction with tritylium cations, react similarly to give 5-substituted 1,3-cyclo-hexadienes, and neutral tricarbonyl(r 4-l,3-cyclohexadiene)iron complexes can be coupled with olefins by hydrogen transfer at > 140°C. These reactions proceed regio- and stereospecifically in the successive cyanide addition and spirocyclization at an optically pure N-allyl-N-phenyl-1,3-cyclohexadiene-l-carboxamide iron complex (A.J. Pearson, 1989).

Me3SiPPh2 assists in the insertion of CO into the Mn-R bond or RMn(CO)5 (R = alkyl or aryl) followed by silyl migration to oxygen. With Mn(CO)5H, however, only cis-substitution by the phosphine occurs, while with the cyclopentadienyl metal tricarbonyl hydrides, silylation occurs at the metal (Scheme 23)92. 

Treatment of q" -l,2,5,6-cyclo-octatetraenecobalt(r -cyclopentadienyl) with methylene iodide and a zinc-copper couple gave the bis-CH2 adduct (209, 19%) whereas similar treatment of r -l,2,3,4-cyclo-octatetraeneiron tricarbonyl gave a mixture of unchanged starting material and ring-expanded adduct (210 25%). ...
