Abstract
Manganese(II) halogeno complexes containing a neutral tris(3,5-diisopropyl-1-pyrazolyl)methane (referred to as L1′) ligand have been examined on their catalytic performance in ethylene polymerization and ethylene/1-hexene copolymerization. The activities of [Mn(Cl2)(L1′)] (a) and [Mn(Br)(L1′)](Br) (b) activated by Al(i-Bu)3/(Ph3C)[B(C6F5)4] for ethylene polymerization go up to 1600 and 840 kg mol (cat)−1 h−1 with a bimodal molecular weight distribution (Mw/Mn) of 4.1 and 4.2, respectively. These results are different from the corresponding manganese(II) complexes with hydrotris(pyrazolyl)borate anion.
