  Synthesis and site-selective protonation of MoPt and WPt bimetallic complexes

  摘要：

  The reaction of [M(cp)(CO)3(PPh2H)]PH6 1 (M = Mo or W, cp = eta-C5H5) with [Pt(C2H4)(PPh3)2] proceeds rapidly with a 1 : 2 (M : Pt) stoichiometry to give [(OC)2(cp)M(mu-PPh2)Pt(CO)(PPh3)] 4 and [PtH(PPh3)3]PF6 5. However, using an initial 1 : 1 stoichiometry the final product is [(OC)2(cp)M(mu-H)-(mu-PPh2)Pt(PPh3)2]PF6 8. The mechanisms of these reactions are shown to involve deprotonation of 1 to give [(OC)3M(cp)(PPh2)] 2 followed by reaction of the latter with [Pt(C2H4)(PPh3)2] and subsequent transfer of CO from M to Pt to give 4. Protonation of 4 with HBF4 is metal (M) dependent and proceeds to give [(OC)2(cp)Mo(mu-H)(mu-PPh2)Pt(CO)(PPh3)]BF4 12a with M = Mo but for M = W the major product is [(OC)2H(cp)W(mu-PPh2) Pt(CO)(PPh3)] BF4 13b. Variable-temperature H-1 NMR studies show that the terminal hydride cation of 13b is rapidly equilibrating with a small amount of the hydride-bridged isomeric cation [(OC)2(cp)W(mu-H)(mu-PPh2)Pt(CO)(PPh3)]+. Complex 4 reacts with PPh3 (60-degrees-C) and 1,2-bis-(diphenylphosphino)ethane (dppe) at 20-degrees-C to give [(OC)2(cp)M(mu-PPh2)Pt(PPh3)2] 9 and [OC2(cp)-M(mu-PPh2)Pt(dppe)] 10. On bubbling CO through a solution of 9 (20-degrees-C) complex 4 is rapidly regenerated. Reaction of 4 with HCl gives [(OC)2(cp)M(mu-H)(mu-PPh2)PtCl(PPh3)] 15. The molecular structure of [(OC)2(cp)W(mu-PPh2)Pt(CO)(PPh3)] 4b has been determined by single-crystal X-ray diffraction.

  The platinum(0) complexes Pt(PR3)2 (R3 = (t-Bu)3 and (t-Bu)2Ph) react readily with the ammonium salts NH4X (X = PF6 and ClO4) to give the cationic ammine hydrides trans-[PtH(NH3)(PR3)2]X. Reaction of Pt(PPh3)3 with NH4PF6 affords [PtH(PPh3)3]PF6. The ammine hydrides trans-[PtH(NH3)L2]X are deprotonated and give the Pt(PR3)2 complexes when NH3 is passed through their solutions in acetone; facile deprotonation

  铂（0）络合物Pt（PR 3）2（R 3 =（t-Bu）3和（t-Bu）2 Ph）与铵盐NH 4 X（X = PF 6和ClO 4）容易反应为得到阳离子氨基氢化物反式-[PtH（NH 3）（PR 3）2 ] X。Pt（PPh 3）3与NH 4 PF 6反应得到[PtH（PPh 3）3 ] PF 6。氨基氢化物反式-[PtH（NH 3）L 2当NH 3通过丙酮中的溶液时，] X被去质子化，得到Pt（PR 3）2配合物；通过CO后，胺氢化物也容易发生脱质子反应，得到三核配合物Pt 3（PR 3）3（CO）3。氨基氢化物的二氯甲烷溶液不受NH 3的影响，但CO与这些溶液反应生成羰基氢化物反式-[PtH（CO）（PR 3）2 ] X。氢化物[PtH（PPh 3）3 ] PF 6不与NH 3反应或丙酮或二氯亚甲基中的一氧化碳。报告了所有复合物的质子和31 P- 1 H} NMR光谱参数以及特征红外频率。
