Abstract

Viene descritto un procedimento per la preparazione di un vanadio bis-arene, [V(arene)2], a partire da ossicloruro di vanadio, alluminio metallico, tricloruro di alluminio ed un arene, in cui:- (a) vengono posti a contatto, in un primo stadio di reazione, vanadio ossicloruro (VOCl3), alluminio metallico attivo e alluminio tricloruro, in un arene liquido, per trasformare l'ossicloruro di vanadio in un cloruro di vanadio in stato di ossidazione (III);- (b) viene aggiunto ulteriore alluminio metallico alla miscela di reazione dello stadio (a) per formare il complesso [V(arene)2] + [AlC14] -;- (c) viene aggiunto un etere ciclico o aliciclico liquido al prodotto della reazione dello stadio (b) per ridurre [V(arene)2] + in [V(arene)2]; e - (d) si recupera il vanadio bis-arene [V(arene)2] dal prodotto della reazione dello stadio (c).I vanadio bis-areni così ottenuti sono utili nella preparazione di catalizzatori di polimerizzazione delle olefine.
