Process for producing vanadium-arenes |
| abstract |
Vanadium-arenas [V(arene)2] wherein "arene" means benzene or mono-, di- or poly-(C1-C5)-alkyl-substituted benzene, are prepared by means of a process which comprises: (a) forming a complex: [V(arene)2](+) ~ AlCl4(-) by reacting vanadium trichloride, aluminum metal and aluminum trichloride with one another, by operating in the presence of the selected arene; (b) treating the so obtained complex with an either cyclic or acyclic, liquid aliphatic ether to obtain the reduction of [V(arene)2](+) to [V(arene)2]; and (c) recovering the so separated vanadium-arene. The vanadium-arenes are useful in the preparation of catalysts for olefin polymerization. |
