  具有偶氮吡啶配体的可光转换和pH响应的有机铂（II）配合物

  摘要：

  已经制备了几种具有含偶氮基团的配体的铂（II）配合物，并对其结构进行了表征，并且研究了它们在反式和顺式偶氮基团异构体之间的光开关。阳离子配合物[PtMe（bipy）（4-NC5H4-N = N-4-C6H4X] [PF6]，X = H，OH或NMe2和偶氮配合物[Pt（bipy）（4- H2NC6H4-N = N-C6H5）2] [OTf] 2在365 nm辐照下进行顺式到顺式光转换，复合物[PtMe（bipy）（4-NC5H4-N = N-4-C6H4NMe2] [PF6]也显示出对质子化具有可逆的盐致变色作用，从而得到二价络合物[PtMe（bipy）（4-NC5H4-NH = N-4-C6H4NMe2] 2+。铂（II）络合物中前沿轨道的性质取决于电荷金属-配体键的复杂度和程度。

  Activation of Anisole by Organoplatinum(II) Complexes: Evidence for Rate-Determining C–H Activation

  摘要：

  A study of the basis of selectivity of C-H bond activation of anisole by electrophilic methylplatinum(II) complexes is reported. Anisole reacts with [PtXMe(NN)] in trifluoroethanol solvent to give methane and [PtXAr(NN)], Ar = 2-, 3-, and 4-anisyl, in 90:8:2 ratio when X = HOB(C6F5)(3) and NN = (2-C5H4N)(2)CO (DPK) but not when NN = 2,2'-bipyridine. Similar results are obtained when X = triflate or when NN = (2-C5H4N)(2)NH. Competition between reaction of anisole and anisole-d(8) with [PtXMe(NN)], X = HOB(C6F5)(3) and NN = DPK, in trifluoroethanol gave an isotope effect k(H)/k(D) = 3.6. Several 4-anisyl complexes, [PtClAr(NN)], [PtAr2(NN)], and [PtMeAr(NN)], NN = DPK, DPA, or bipy, were prepared and reacted with HX [X = Cl, OTf, or HOB(C6F5)(3)]. Reaction of [PtMeAr(NN)], NN = DPK or bipy, with HX gave a detectable hydride [PtXHMeAr(NN)] when X = Cl, followed by loss of methane to give [PtClAr(NN)], but only [Pt(OTf)Ar(NN)] was detected when X = OTf. Reaction with more HOTf gave anisole and [PtX2(NN)], X = OTf, and no isomerization of the 4-anisyl group to the more favored 2-anisyl group was observed at any stage. The similar reaction of [PtMeAr(NN)] and HOTf in CD3OD/CD2Cl2 gave CHnD4-n (n = 0-4) and mostly 4-MeOC6H4D. It is argued that the anisole C-H bond cleavage step in anisole activation, or the anisyl-H bond forming step in protonolysis, is responsible for the observed selectivity in these reactions.

  The reactions of dimethylamine-borane with platinum(II) or platinum(IV) triflate complexes gave, not the anticipated σ-complexes, but the respective hydridoplatinum complexes. The reaction with [Pt(OTf)Me3(NN)], with NN = 2,2′-bipyridine (bipy) and 4,4′-di-t-butyl-2,2′-bipyridine (bu2bipy), gave the rare stable bridging hydridoplatinum(IV) complexes [μ-HPtMe3(NN)}2][OTf] and the reaction with [Pt(O2CCF3)Me(NN)]

  nitrogen-protected palladium(II) and platinum(II) complexes have been investigated. While dynamic equilibria between molecular triangles and squares were observed when the diimine compounds 4,4'-R2bipy (bipy = 2,2'-bipyridine; R = H, Me, t-Bu) were employed as ancillary ligands, only square species were obtained from ethylenediamine (en) derivatives. Characterization of the obtained metallomacrocycles was accomplished

  研究了氟化的对位配体1,4-双（4-吡啶基）四氟苯（A）与不同的氮保护钯（II）和铂（II）配合物之间的自组装反应。当使用二亚胺化合物4,4'-R2bipy（bipy = 2,2'-联吡啶； R = H，Me，t-Bu）作为辅助配体时，观察到分子三角形和正方形之间的动态平衡。从乙二胺（en）衍生物获得。通过1H和19F NMR光谱结合电喷雾电离傅立叶变换离子回旋共振质谱（ESI-FT-ICR）对获得的金属大环化合物进行表征。已经执行了分子动力学模拟（UFF）来解释氟化环对方形/三角形相对稳定性的影响。使用GIAO方法的密度函数计算已用于解释化学位移分配。对这些化合物充当富电子芳族客体的主体的能力的研究表明，乙二胺钯方剂能够仅在水性介质中建立这种类型的分子间相互作用。主客体的化学计量和缔合常数已通过1 H NMR光谱法确定。
