摘要：

在此通讯中，我们报告了我们对开发金催化的 C(sp 3 )-H 键直接乙酰氧基化的研究。我们通过使用高价碘试剂 PhI(OAc) 2与简单的金盐 (HAuBr 4 ) 作为催化剂来实现这一点。通过比较环辛烷和金刚烷的反应性，我们判断反应是通过氢化物转移进行的。通过对源自与 CH 裂解步骤相关的环辛烷和金刚烷的 C-H 键裂解的阴离子、自由基和阳离子的相对能量的计算研究，进一步证实了这一点。

Halogen impact into new oxonium benzo-crown ether complexes with tetrachloro- and tetrabromoaurates(iii)

作者：Sergei M. Pluzhnik-Gladyr、Victor Ch. Kravtsov、Marina S. Fonari、Gerbert L. Kamalov

DOI：10.1039/c4dt00017j

日期：——

Five oxonium tetrahalogenaurate(III) (Hal = Cl, Br) benzo-crown ether (BCE) complexes are prepared and reported. The new compounds are [(H3O)(B18C6)0.58(4′-Cl-B18C6)0.42][AuCl4] 1, [(H3O)(B18C6)][AuCl4] 2, [(H3O)(4′-Br-B18C6)][AuCl4] 3, [(H3O)(4′-Br-B18C6)][AuBr4] 4, and [(H3O)(B18C6)][AuBr4] 5. The reaction medium, distinctive from the previously used aqua regia, allowed avoiding the unwanted nitration of initial macrocycles. The compositions and structures for 1, 3, 4, and 5 were proved by single crystal X-ray crystallography. The complete conversion of tetrachloroaurate(III) to the tetrabromoaurate(III) salts resulted in complex 4 isomorphous and isostructural to 3. All compounds form the laminated structures with alternation of cationic and anionic layers. The robustness of the anionic sheets is sustained by the halogen–halogen interactions and makes crucial impact on extraction of stoichiometric products in the case of tetrabromoaurate(III) salts.

by alloying with [AuI(PPh3)Br]. The structures of the trimetallic NCs were determined by X‐ray crystallography and further confirmed by both DFT and far‐IR measurements. The shape‐preserved [Pt1Au6.4Ag17.6(SPhMe2)18] NC is in a tristratified arrangement—[Pt(center)@Au/Ag(shell)@Ag(exterior)]—and is indeed the first X‐ray crystal structure of thiolated trimetallic NCs. On the other hand, the resulting

具有精确原子排列的形状受控的金属纳米团簇（NC）的合成对于定制性能至关重要。在这项工作中，我们通过在合金化过程中改变掺杂剂来成功控制合金NC的形状。当使用[Au I SR]作为掺杂剂时，球形[Pt 1 Ag 24（SPhMe 2）18 ] NC的形状得以保持。相反，通过与[Au I（PPh 3）Br]合金化，Pt 1 Ag 24的形状变为棒状。三金属NC的结构通过X射线晶体学确定，并通过DFT和远红外测量进一步证实。保形[Pt 1Au 6.4 Ag 17.6（SPhMe 2）18 ] NC是三层结构的[Pt（中心）@ Au / Ag（壳）@Ag（外部）]，并且确实是硫代三金属NC的第一个X射线晶体结构。。另一方面，所得的棒状NC（[Pt 2 Au 10 Ag 13（PPh 3）10 Br 7 ]）显示出高量子产率（QY ＝ 14.7％），这与微弱发光的Pt 1 Ag形成鲜明对比。24（QY
Macrocyclic Receptor for Precious Gold, Platinum, or Palladium Coordination Complexes

作者：Wenqi Liu、Allen G. Oliver、Bradley D. Smith

DOI：10.1021/jacs.8b04155

日期：2018.6.6

Two macrocyclic tetralactam receptors are shown to selectively encapsulate anionic, square-planar chloride and bromide coordination complexes of gold(III), platinum(II), and palladium(II). Both receptors have a preorganized structure that is complementary to its precious metal guest. The receptors do not directly ligate the guest metal center but instead provide an array of arene π-electron donors
