Streszczenie

The direct reaction between [VCl3(thf)3] or [VO(OEt)3] and 2,2′-thiobis{4-(1,1,3,3-tetramethyl-butyl)phenol (tbopH2) leads to the formation of [V2(µ-tbop-κ3O,S,O)2Cl2(CH3CN)2] (1)·4CH3CN or [V2(µ-OEt)2(O)2(tbop-κ3O,S,O)2] (2), respectively, in high yield. Compounds 1 and 2 were characterized by chemical and physical techniques including X-ray crystallography and variable temperature magnetic susceptibility studies (J = −29.1 cm−1) for 1. Complexes 1 and 2 were supported on MgCl2 and when activated with aluminium alkyls, were found to effectively polymerize ethene to produce polyethylene with a narrow molecular weight distribution Mw/Mn ∼ 3.
