  [PtOTf(triphos)]OTf and [PtMe2(triphos-P,P′)] as versatile synthons of platinum(II)-triphos species

  摘要：

  The new complex [PtOTf(triphos)]OTf (triphos = bis(2-diphenylphosphinoethyl)phenyl-phosphine, OTf = CF3SO3) (1) can be most efficiently prepared by adding triflic acid to the known complex [PtMe2(triphos-P,P')] (5) where triphos acts as a bidentate ligand. The fluxional behaviours of 1 and 5 in solution and their reactivity have been investigated by NMR: [PtOTf(triphos)]OTf is a very electrophilic complex and its reactivity is dominated by the tendency of the labile ligand OTf to be replaced by a variety of nucleophiles, while the chemistry of [PtMe2(triphos-P,P')] is controlled by the proclivity of the third phosphorus to coordinate to platinum, as soon as a vacancy is created via Pt-Me protonolysis.

  linear triphosphine triphos [=bis(diphenylphosphinoethyl)phenylphosphine] acts as a bidentate ligand, can be easily converted in a variety of new complexes due to the reactivity of the free phosphorus donor. The selective oxidation of the uncoordinated phosphorus gave [PtMe2(triphosPO-P,P′)] whose X-ray crystal structure is here reported; from the reactions of 1 with platinum and non platinum precursors

  摘要配合物[PtMe2（triphos-P，P'）]，（1）其中线性三膦三[[双（二苯基膦基乙基）苯基膦]充当双齿配体，由于其反应活性，可以很容易地转化为多种新配合物游离磷供体。对未配位的磷的选择性氧化得到了[PtMe2（triphosPO-P，P'）]，其X射线晶体结构已在此处报道。1与铂和非铂前体均三金属[Pt3Me4XY（triphos）2]（X = Y = Me，Cl，I，X = Me，Y = Cl）和杂三金属（[Pt2PdMe4Cl2（triphos）2]和获得了Pt2RhMe4（cod）（triphos）2] PF6）配合物，其中三氯甲烷起着螯合/桥联配体的作用。当在中性电子供体L（L = SMe2，吡啶，PPh3）存在下用三氟甲磺酸处理1时，复合物[PtL（triphos）] 2+可以快速回收。

  diorganoplatinum(II) complexes [PtR2(triphos-P,P′)] (1; R = Me, p-MeC6H4 and triphos = bis(2-(diphenylphosphino)ethyl)phenylphosphine), containing one free phosphine atom, react with cyclometalated platinum complexes [PtR′(C∧N)(SMe2)] (2; R′ = Me, p-MeC6H4 and C∧N is deprotonated 2-phenylpyridine (ppy) or deprotonated benzo[h]quinoline (bhq)) to give the cyclometalated diplatinum(II) complexes [Pt2R2R′(C∧N)(triphos)]

  二有机铂（II）配合物[PTR 2（triphos -P，P'）]（1 ; R = Me，p -MeC 6 H 4和triphos =双（2-（二苯基膦基）乙基）苯基膦），含一个游离膦原子，与环金属铂络合物[PTR'（C反应∧ N）（SME 2）]（2 = Me中，; R' p -MeC 6 ħ 4和C ∧ N被去质子化的2-苯基吡啶（PPY）或去质子化的苯并[ ħ ]喹啉（BHQ）），得到环金属二铂（II）配合物[PT 2 - [R 2 R'（C ∧ N）（三膦）]（3）。在这些双核铂（II）化合物中，三价硫同时充当螯合和桥联配体，以稳定产生的双铂配合物。配合物3通过多核NMR光谱法和元素微量分析容易地表征。复合物的晶体结构3F（R = Me中，R'= p -MeC 6 ħ 4和C ∧ N = BHQ）通过X射线结晶学测定进一步，给出的X射线结构测定的第一个例子具有三价配体的双铂配合物，同时充当螯合和桥联配体。
