Titanocene- and Zirconocene(diazadiene) Complexes: Preparation, Characterization, and StructureBy treating Cp2MCl2 (M = Ti, Zr) with magnesium in the presence of the diazadienes R1N = CR2CR2 = NR1 (R1 = R2 = Ph:1a; R1 = Ph, R2 = Me: 1b) metallocene complexes of formula Cp2) (M = Ti: 2a, b; M = Zr: 3a, b) have been obtained in good yields. 2a-3b exhibit dynamic NMR spectra indicating a rapid intramolecular migration of the bent metallocene unit Cp2M from one “face” of the reduced diazadiene to the other. From the 1H-NMR Cp-coalescence ΔG
