ChemInform Abstract
On reduction of (I) with Mg in the presence of equimolar amounts of ( II), the title complexes (III) are formed, which exhibit dynamic NMR spectra indicating a rapid intramolecular migration of the metallocene unit Cp2M from one “face” of the reduced diazadiene to the other. Activation energies of this automerization process are given. (IIIb) is characterized by X-ray diffraction (P21/c, Z = 4).
