Synthesis and catalytic activity of camphor titanium complexes

Popis výsledku v původním jazyce

Three new camphor-titanium complexes [TiClCp2L] (L = L-1, (1); L-2, (2) and (LH)-L-3 (3)) were obtained through replacement of one chloride by a camphor-type ligand ((LH)-L-1, (LH)-L-2, (LH2)-L-3 (3)) at the coordination sphere of [TiCl2Cp2]. Complexes 1and 2 were structurally characterized by X-ray diffraction analysis showing that coordination occurs through the oxygen atom of the hydroxo group (1) with cooperative coordination of the nitrogen atom of the oxime complex in 2. Upon activation with MAOcomplexes 1 and 2 promote ethylene polymerization and ethylene/norbornene co-polymerization while compound 3 displays no catalytic activity for either one or the other process. At 50 degrees C the catalytic activity complex of 2 (852 kg(PE) mol (1) h (1)) for ethylene polymerization is higher than that of compound 1 (668 kg(PE) mol (1) h (1)) which is similar to that of [TiCl2Cp2] (670 kg PE mol (1) h (1)). The catalytic activity of complex 1 displays a higher dependence on the temperatu
