m.r. spectra are discussed, and it is suggested that the bis- and tris-(trifluoromethyl)-substituted fluorophosphates have a trans configuration.Trimethyltrifluoromethyltin, (CH3)3SnCF3, forms 1:1 complexes with PF5, (CF3)2PF3, and (CF3)3PF2. It is suggested that transfer of a trifluoromethyl group as CF3− has occurred here, leading to the formation of trimethyltin derivatives of the trifluoromethyl-substituted
合成路线已开发到含有阴离子 [CF3PF5]-、[(CF3)2PF4]-、[(CF3)3PF3]-、[(CF3)2AsF4]- 和 [(CF3)3AsF3]- 的盐。它们被分离为稳定的固体,以 Cs+ 或有时是 Ag+ 作为阳离子。讨论了它们的 19F 核磁共振谱,并表明双-和三-(三氟甲基)-取代的氟磷酸盐具有反式构型。三甲基三氟甲基锡、(CH3)3SnCF3 与 PF5、(CF3)2PF3 和 (CF3)2PF3 形成 1:1 配合物。 (CF3)3PF2。这表明这里发生了三氟甲基作为 CF3- 的转移,导致三氟甲基取代的氟磷酸盐的三甲基锡衍生物的形成。
