The new compound meso-ethylenebis (4,7-dimethyl-1-indenyl) zirconium dimethyl (1-Me2) has been prepared and a detailed structural investigation by 2D-NMR has been performed, using COSY gs, NOESY, HBMCgs and HSQCgs spectra. These experiments allowed us to perform the full 1H and 13C NMR spectral assignments. We also detected long distance interactions between the methyl protons on the metal centre and carbon atoms in the indenyl system. A qualitative MO analysis has been performed in order to clarify the experimental evidence.

Abstract
The new compound meso-ethylenebis (4,7-dimethyl-1-indenyl) zirconium dimethyl (1-Me2) has been prepared and a detailed structural investigation by 2D-NMR has been performed, using COSY gs, NOESY, HBMCgs and HSQCgs spectra. These experiments allowed us to perform the full 1H and 13C NMR spectral assignments. We also detected long distance interactions between the methyl protons on the metal centre and carbon atoms in the indenyl system. A qualitative MO analysis has been performed in order to clarify the experimental evidence.File in questo prodotto:
