Synthesis, characterization and catalytic activity of some organolanthanides in ethylene polymerization

The synthesis and characterization of a new class of organolanthanide compounds containing the bromide and cyclopentadienyl anions together with a pyrazinamide ligand are presented. The compounds were characterized by elemental analyses, complexometric titration with EDTA, thermal analyses, vibrational spectra in the infrared region. The catalytic activity of these compounds in ethylene polymerization was examined.
