Abstract
The reactions of Schiff bases, derived by the condensation of thiophene-2-aldehyde with ethylenediamine,o-phenylenediamine or 4-methyl-o-phenylenediamine withbis-(cyclopentadienyl)titanium(IV)/zirconium(IV) dichloride have been studied in refluxing THF in the presence and absence of base. Two types of derivatives [Cp2MCl2·L] and [(Cp2MCl)2L]Cl2 have been isolated and characterized by elemental analyses, electrical conductance, magnetic moment and spectral (electronic, i.r.,1H n.m.r. and13C n.m.r.) studies.1H and13C n.m.r. spectra reveal rapid rotation of the cyclopentadienyl ring around the metal-ring axis (n.m.r. time scale) at 25°C. Probable structures for the complexes are proposed.
