摘要：

New complexes of the type F(2)RPAuCF(3) (R = (t)Bu, NEt(2), NMe(2), Ph, Cp, F) (I-VI) have been prepared in good yield and characterized fully. Gold(I)chloride reacts with the corresponding fluorphosphine in an organic solvent leading to the chloro-fluorophosphine compounds F(2)RPAuCl (R = (t)Bu, NEt(2), NMe(2), Ph, Cp, F) (VII-XII). These react in a second step with Cd(CF3)(2) yielding the corresponding trifluormethyl-fluorphosphine complexes (I-VI). Following this route trifluormethyl(trifluorophosphine)gold(I), F3PAuCF3 (VI), was prepared. Although it is thermally unstable this compound was successfully characterized by mass spectrometry. The compositions and structures of the other complexes were determined by elemental analyses, IR, AAS (VII-XI), H-1-, F-19- and P-31-NMR spectroscopies and mass spectometry (I-XI).
