The complexes (C5H5)2VIIIR, where R pentafluorophenyl, cyclopentadienyl allyl, 2-methylalyl and 2-butenyl, were prepared by reaction of one mole of (C5H5)2VIIICl with one mole of C5F5Li, C5H5Na, or (methyl)allylmagnesium halide in tetrahydrofuran or diethyl ether. The pentafluorophenyl complex is very stable, but the other complexes had to be prepared and stored below room temperature. The complexes
通过使一摩尔(C 5 H 5)2 V III Cl与一摩尔反应制备配合物(C 5 H 5)2 V III R,其中R 1五氟苯基,环戊二烯基烯丙基,2-甲基丙烯基和2-丁烯基。的C 5 F 5 Li,C 5 H 5Na,或在四氢呋喃或乙醚中的(甲基)烯丙基卤化镁。五氟苯基配合物非常稳定,但其他配合物必须制备并在室温以下保存。该络合物对氧非常敏感。每个分子有两个不成对的电子。红外和质子磁共振光谱表明,配体R是σ键合到金属上的。
