Abstract

Abstract : LiNTf2 adds to a zwitterionic fulvalene yielding a η 5 -CpLi complex that is in equilibrium with its lithiocene at −80 °C as revealed by 7 Li NMR spectroscopy. Abstract : The synthesis of a η 5 -coordinated LiCp complex by simple addition of a Li-salt in benzene is presented. A strongly zwitterionic fulvalene serves as the Cp-precursor. Evidence for the coordination of Li + was obtained by the characterisitic 7 Li NMR chemical shifts, variable temperature experiments in solution and by X-ray structure analysis in the solid state.
