trifluoromethyl elemental compounds Me2PP(CF3)2 and Me2AsP(CF3)2 have been studied by the synthesis and spectroscopic investigations (IR, NMR, MS) of their complexes cis-M(CO)4L2 (A), [(CO)4ML]2 (B) and [(CO)5M]2L (C) (M = Cr, Mo, W). Complexes of type A with L = Me2PP(CF3)2 are obtained in good yield by reaction with M(CO)4NBD (NBD = norbornadiene), whereas with L = Me2AsP(CF3)2 the homobinuclear compounds B
三氟甲基元素化合物Me 2 PP(CF 3)2和Me 2 AsP(CF 3)2的配位性质已通过其配合物顺式-M(CO)的合成和光谱研究(IR,NMR,MS)进行了研究。4 L 2(A),[(CO)4 ML] 2(B)和[(CO)5 M] 2 L(C)(M = Cr,Mo,W)。L = Me 2 PP(CF 3)2的A型配合物通过与M(CO)4 NBD(NBD =降冰片二烯)反应,以高收率获得三价铁,而与L = Me 2 AsP(CF 3)2则形成同双核化合物B。通过用P 2(CF 3)4处理M(CO)4(Me 2 AsH)2来制备顺式-M(CO)4 [Me 2 AsP(CF 3)2 ] 2配合物的尝试仅对M成功。 = W. B或C型双核化合物通常,可以通过使配体与M(CO)4 NBD或M(CO)5 THF逐步反应来制备。
