This article concerns methods of synthesis, structural and catalytic characterisation of titanium complexes based on the 2,2'-thiobis{4-(1,1,3,3-tetramethyl-butyl)phenolato (tbop) ligand. In recent years there is a growing recognition that nonmetalocene complexes hold great promise as olefin polymerization catalysts. Most successful developments in terms of catalysis have appeared using chelating bis(aryloxide) ligands, in particular with tridentate and tetradentate ligands having an additional coordinating heteroatoms (N, O, S). The tbop ligand was placed on Ti and several heteroleptic, alkoxo- and aryloxo-bridged complexes containing coligands like chlorides, imides, monoaryloxides as well as homoleptic compound have been prepared and structurally characterised. These complexes when activated with aluminum alkyls are highly effective heterogeneous, well-defined, single-site ethene polymerization catalysts.
