Fecha de publicación: | 21-abr-2010 | Editor: | Elsevier | Citación: | Journal of Organometallic Chemistry 695(14): 1794-1800 (2010) | Resumen: | The catalytic activities of the highly fluorous systems formed by the zirconocene(IV) complexes [Zr{η5-C5H4SiMe2C2H4RF}2Cl2] (RF = C6F13 (4a), C10F21 (4b)) or [Zr-{η5-C5H3(SiMe2C2H4C6F13)2}2Cl2] (5a) and MMAO in toluene have been studied and compared with analogous nonfluorous systems generated from [Zr{η5-C5H4SiMe3}2Cl2] and [Zr{η5-C5H5}2Cl2]. Although less active than the reference systems, the fluorous catalysts are stable over prolonged polymerization times, giving rise to polymers with similar molecular weights to those obtained with [Zr{η5-C5H4SiMe3}2Cl2]. | Descripción: | 7 páginas, 3 figuras, 2 tablas, esquemas. | Versión del editor: | http://dx.doi.org/10.1016/j.jorganchem.2010.03.030 | URI: | http://hdl.handle.net/10261/37443 | DOI: | 10.1016/j.jorganchem.2010.03.030 | ISSN: | 0022-328X |
