Ferrocenylalanes: solid-state and solution structures of some new aluminum-bridged ansa-ferrocenes.
Addition of dilithiated ferrocene to AlEt2Cl and Al(kappa2-C,NNMe2CH2C6H4)Cl2 yields the trimeric ferrocenyl derivative 1 and the dimeric [1,1']-ferrocenophane 2, respectively. Solution spectroscopy is consistent with the solid-state structures, which reveal unusual and unprecedented bonding around the aluminum centers.
