[1,8-C10H6(NR)2]TiCl2 (3; R = SiMe3, Si(i)BuMe2, Si(i)Pr3) complexes have been prepared from dilithio salts [1,8-C10H6(NR)2]Li2 (2) and TiCl4 in diethyl ether in moderate yields (60-63%). These complexes showed significant catalytic activities for ethylene polymerization and for ethylene/1-hexene copolymerization in the presence of methylaluminoxane (MAO), methyl isobutyl aluminoxane (MMAO), Al(i)Bu3- or AlEt3-Ph3CB(C6F5)4 as a cocatalyst. The catalytic activities performed in heptane (cocatalyst MMAO) were higher than those carried out in toluene (cocatalyst MAO): 709 kg-PE/mol-Ti · h could be attained for ethylene polymerization by using [1,8-C10H6(NSi(i)BuMe2)2]TiCl2-MMAO catalyst system.
