Intramolecular nucleophilic attack has been demonstrated in several cases, particularly with amine and (rj -allyl)Fp complexes an example of the former is depicted (equation 20). In such cases, the driving force for formation of five- or six-membered rings overrides the preference for attack at the more substituted alkene center. The ability of trialky-lamines to convert (> -aIkene)Fp+ complexes into (rj -allyl)Fp complexes via deprotonation allows conversion of alkadiene complexes (see Diene Complexes) (96) into carbocycles (97,98). The reasons for the stereochemical outcome of these cyclization reactions have not been fully delineated. Finally, ( ) -butadiene)Fp+ cations react in two sequential ( ) -allyl)Fp-( -alkene)Fp+ pairs to give a mixture of cyclic...
