%X The effect of ligand and Al cocatalysts in ethylene polymerization, using V( N-1-adamantyl)Cl 2(L) [L = 2-(2,6-Me 2C 6H 3)NCH 2(C 9H 6N), 8-(2,6-Me 2C 6H 3)NCH 2(C 9H 6N)] and V( N-2-MeC 6H 3)Cl 2[2-(2,6-R' 2C 6H 3)NCH 2(C 5H 4N)] (R' = Me, iPr), has been explored. The reaction products in the presence of Et 2AlCl or Me 2AlCl cocatalyst were polyethylene whereas the reaction product of the 2-methylphenylimido analogues in the presence of MAO cocatalyst was 1-butene with high selectivity, suggesting that the catalyst/cocatalyst nuclearity effect plays a role in this catalysis.
