Title (EN) PROCESS TO PREPARE BRIDGED PHOSPHOLE-CYCLOPENTADIENYL COMPOUNDS
(FR) PROCEDE DE PREPARATION DE COMPOSES PHOSPHOLE-CYCLOPENTADIENYLE PONTES
Abstract:
(EN) A new family of phospholes having a metalloid bridge to a cyclopentadienyl group is prepared by reacting an organometallic cylcopentadienyl reagent with a 'halogenated phosphole' (having a halogen or pseudohalogen group). The new phospholes may be used to prepare organometallic phospholyl complexes. Group 4 metal complexes of these phospholes are excellent polymerization catalysts, especially for the polymerization of olefins at high temperature.
(FR) On prépare une nouvelle famille de phospholes renfermant un pont métalloïde avec un groupe cyclopentadiényle en faisant réagir un réactif cyclopentadiényle organométallique avec un 'phosphole halogéné' (contenant un halogène ou un groupe pseudo-halogène). Ces nouveaux phospholes peuvent être utilisés pour préparer des complexes phospholyle organométalliques. Les complexes avec un métal du groupe 4 de ces phospholes sont d'excellents catalyseurs de polymérisation, notamment pour la polymérisation des oléfines à haute température.
