Alkenes in (alkene)dicarbonyl(T -cyclopentadienyl)iron(l+) cations react with carbon nucleophiles to form new C —C bonds (M. Rosenblum, 1974 A.J. Pearson, 1987). Tricarbon-yi(ri -cycIohexadienyI)iron(l-h) cations, prepared from the T] -l,3-cyclohexadiene complexes by hydride abstraction with tritylium cations, react similarly to give 5-substituted 1,3-cyclo-hexadienes, and neutral tricarbonyl(n -l,3-cyciohexadiene)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). 

Early ab initio HF-LCAO calculations using minimal basis sets were at first thought to have been unsuccessful, in that they gave the polarity C-O", whilst HF-LCAO calculations with extended basis sets gave the polarity C O-. That the polarity is indeed C-O" " was shown by Rosenblum, Nethercott and Townes (1958) from a molecular beam resonance experiment it goes against all chemical inmition.
