  正和异全氟丙基碘化物和正全氟丁基碘化物在室温下取代二甲基铂 (II) 1,5-环辛二烯：[Pt(C3F7)2(COD)] 的晶体结构

  摘要：

  摘要 二甲基铂 (II)COD [COD = 1,5-环辛二烯] 与摩尔过量的全氟正丙基碘在室温下反应生成 [Pt(C 3 F 7 ) 2 (COD)]。全氟异丙基碘和全氟正丁基碘生成单取代基 [Pt( i -C 3 F 7 )(CH 3 )(COD)] 和 [Pt(C 4 F 9 )(CH 3 )(COD) ]，分别与抑制第二次取代反应的空间位阻一致。[Pt(C 3 F 7 ) 2 (COD)] 的晶体结构揭示了铂的方形平面几何形状。

  2 nm. Furthermore, substitution of the CH3 end group by the CnF2n+1 end groups led to a significant drop in Pt loading of about 50 %. Within the series of perfluorinated end groups that were considered, the Pt complex that contained a branched perfluoro‐isopropyl group showed the most‐interesting results when compared to the control precursor, [Pt(cod)Me2] (1).

  提出了一系列包含不同全氟烷烃链[Pt（cod）Me（C n F 2 n +1）]的环辛二烯稳定的Pt配合物的优化合成。这些金属有机化合物被用于还原条件下在CO 2中所谓的超临界流体反应沉积（SFRD），以在氧化铝上作为多孔载体生成金属纳米颗粒。因此，获得了具有窄粒度分布的Al 2 O 3负载的Pt纳米颗粒。在15.5 MPa的减压压力和353 K的温度下，d 50的粒径产生了= 2.3–2.8 nm。在还原反应过程中降低压力会导致颗粒稍大，同时减少CO 2中有机金属前体的量会使粒径从x 50 = 3.2 nm减小到2.6 nm，粒径分布为2.2 nm。此外，CH 3端基被C n F 2 n +1端基取代导致Pt载量显着下降约50％。在考虑的一系列全氟端基中，与支链前体[Pt（cod）Me 2 ]相比，包含支链全氟异丙基的Pt络合物显示出最有趣的结果。1）。

  The UV irradiation of a mixture of PtMe2(cod) (cod = 1,5-cyclooctadiene) and n-C4F9I in a 1:12 molar ratio for 15 min produces Pt(n-C4F9)(2)(cod) in 61% yield at room temperature. The reaction without irradiation, as reported previously, proceeds much more slowly; heating the mixture for 7 days at 50 degrees C forms PtMe(n-C4F9)(cod) in 9% yield and no Pt(n-C4F9)(2)(cod). Pt(n-C4F9)(2)(cod) is converted to complexes having chelating ligands, Pt(n-C4F9)(2)(L) (L = dppe (1,2-bis(diphenylphosphino)ethane), dppp (1,3-bis(diphenylphosphino)propane), bpy (2,2'-bipyridine)). The photoassisted fluoroalkylation of PtMe(n-C4F9)(cod) also affords Pt(n-C4F9)(2)(cod), while the monomethylplatinum complexes PtMe(C6H4-4-F)(cod) and PtClMe(cod) react with n-C4F9I under photoirradiation to afford complexes with a perfluorobutyl ligand, Pt(n-C4F9)(C6H4-4-F)(cod) and PtCl(n-C4F9)(cod), respectively. The above reactions do not provide isolable Pt(IV) complexes, in contrast to the reactions of alkyl or fluoroalkyl iodides with diorganoplatinum(II) complexes having dinitrogen ligands. The mechanism of the fluoroalkylation of Pt(II) complexes under photoirradiation is discussed on the basis of the reaction products.

  Reaction of (COD)PtMe2 (COD = 1,5-cyclooctadiene) with one molar equivalent of C4F9I in hexanes produces the perfluoroalkylplatinum product (COD)PtMe(C4F9) (1) along with the known Pt(IV) complex [PtMe3I](4). This result stands in contrast to previous reports that attempts to synthesize platinum complexes with fluoroalkyls larger than CF3 gave only inseparable mixtures. An essential condition to the controlled synthesis of 1 is the use of only one equivalent of perfluoroalkyl iodide. Similar reactions reported previously employed an excess of iodoperfluorocarbon, which gave rise to mixtures of products due to successive oxidative addition and reductive elimination reactions. The X-ray crystal structure (COD)PtMe2 was determined. (C) 2002 Elsevier Science Ltd. All rights reserved.
