Language eng - English Country CH - Switzerland Keywords titanocene ; zircocene ; polymerization Subject RIV CF - Physical ; Theoretical Chemistry R&D Projects KSK4050111 GA AV ČR - Academy of Sciences of the Czech Republic (AV ČR) Annotation An easy and inexpensive three-step synthesis of new 2,3-dimethyl-1,4-diphenylcyclo-pentadiene (3) ligand and the titanium (4) and zirconium (5) homometallocene dichlorides and the mixed ligand zirconium complex [ZrCl2(.eta.5-C5H-2,3-Me2-1,4-Ph2)(.eta.5-C5H5)] (6) prepared thereof are described. The polymerisation of ethene using 4 - 6/MAO catalysts revealed that zirconocene complexes 5 and 6 displayed moderate and high activity, respectively, whereas the titanium catalyst 4/MAO was inactive. The crystal structures of 4 and 5 have been determined by X-ray crystallography. Workplace J.
