Reactions between bis(pentafluorophenyl)phosphine and Group VI metal carbonyls have been investigated and the mono-, di- and tri-substituted complexes [(C6F5)2PH]M(CO)5(M = Cr, Mo, W), [(C6F5)2PH]2M(CO)4(M = Cr, Mo), and [(C6F5)2PH]3Mo(CO)3 characterised. Treatment of the monosubstituted chromium and molybdenum complexes with n-butyl-lithium affords (C6F5)2P(Li)M(CO)5(M = Cr, Mo). Reaction of tetr
已经研究了双(五氟苯基)膦与VI族金属羰基化合物之间的反应,以及单,双和三取代的配合物[(C 6 F 5)2 PH] M(CO)5(M = Cr,Mo,W ),[[C 6 F 5)2 PH] 2 M(CO)4(M = Cr,Mo)和[(C 6 F 5)2 PH] 3 Mo(CO)3为特征。用正丁基锂处理单取代的铬和钼络合物得到(C 6 F 5)2 P(Li)M(CO)5(M = Cr,Mo)。四(五氟苯基)二膦与Cr(CO)6和Mo(CO)6的反应生成聚合物络合物[(C 6 F 5)4 P 2 M(CO)4 ] n(M = Cr,Mo),收率低单取代的配合物[(C 6 F 5)2 PH] Mo(CO)5的合成。阴离子[M(CO)5 ] 2–(M = Cr,Mo)与(C 6 F 5)2 PCl反应,得到单取代的二膦配合物(C 6 F 5)4P 2 M(CO)5。铬配合物也由(C 6 F 5)2
