  [（C 2 F 5）2 MeP] 2 Pt（Me）X（X = Me，O 2 CCF 3，OTf，OSO 2 F）的合成和反应性：与螯合物受体类似物的反应性比较

  摘要：

  新型铂甲基配合物cis-（dfmp）2 Pt（Me）2和反式-（dfmp）2 Pt（Me）X的比较研究（dfmp =（C 2 F 5）2 MeP; X = O 2 CCF 3， OTf，OSO 2 F）与先前报道的受体螯合物类似物（dfepe）Pt（Me）X（dfepe =（C 2 F 5）2 PCH 2 CH 2 P（C 2 F 5）2 ; X = Me，O 2 CCF 3，OTf，OSO 2F）被提出。与对H 2和CO均呈惰性的（dfepe）Pt（Me）2相比，顺式（dfmp）2 Pt（Me）2容易反应形成（dfmp）4 Pt和顺式（dfmp）（分别为CO）Pt（Me）2。同样，（dfepe）Pt（Me）2在高达180°C的温度下仍稳定，而顺式（dfmp）2 Pt（Me）2在80°C的苯-d 6中的热分解导致乙烷还原消除并生成（ dfmp）4分。溶解顺式-（dfmp）2 Pt（Me）2

  The comparative reactivity properties of previously reported trans-(dfmp)(2)Pt(Me)X (dfmp = (C2F5)(2)-MeP; X = O2CCF3, OTf, OSO2F) with small molecules are presented. Anionic ligand displacement by CO depends upon X and the corresponding acid solvent. In trifluoroacetic acid, treatment of trans(dfmp)(2)Pt(Me)(O2CCF3) with CO results in loss of dfmp to form the mixed phosphine/carbonyl product (dfmp)(CO)Pt(Me)(O2CCF3). However, in triflic and fluorosulfonic acids trans-(dfmp)(2)Pt(Me)(X) compounds react with CO to form trans-(dfmp)(2)Pt(Me)(CO)(+)(X)(-). trans-(dfmp)(2)Pt(Me)(X) systems react with H-2 under both acidic and aprotic conditions to form trans-(dfmp)(2)Pt(H)(X); trans-(dfmp)(2)Pt(H)(OTf) has been crystallographically characterized. Treatment of trans-(dfmp)(2)Pt(H)(OTf) with CO or dfmp gives trans-(dfmp)(2)Pt(H)(CO)(+) or (dfmp)(3)Pt(H)(+), respectively. In contrast to trans-(dfmp)(2)Pt(Me)(OTf), which releases methane in HOTf, trans-(dfmp)(2)Pt(Me)(OSO2F) in FSO3H at 80 degrees C cleanly produces the reductive elimination product MeOSO2F. Carbonylation of trans-[(dfmp)(2)PtMe(CO)]X-+(-) under 1000 psi CO in turn cleanly produces MeC(O)X at ambient temperatures. The mechanism of reductive elimination from these Pt(II) precursors is discussed.
