  Structures, electrochemical and spectroscopic properties of ternary ruthenium(II)-polypyridyl complexes with additional carboxylate, biguanide or sulfonamide donors

  摘要：

  The following complexes have been prepared: [Ru(bipy)(2)(pic)][PF6] (bipy = 2,2'-bipyridine; Hpic = picolinic acid); [Ru(terpy)(dipic)] (terpy =2,2':6',2"-terpyridine; H(2)dipic=dipicolinic acid); [Ru(bipy)(2) (Hbig)][PF6](2) (Hbig=biguanide); and [Ru(bipy)(2)(apps)][PF6] [where Happs is the p-tolylsulfonamide of 2-(2-aminophenyl)-pyridine]. The latter three have been characterised by X-ray crystallography and are all mononuclear pseudo-octachedral complexes. Electrochemical studies reveal the relationship between the potential of the metal-based Ru(II)/Ru(III) couple, with the potential values being clearly related to the sigma-donor or pi-acceptor capabilities of the ligands. The energies of the lowest-energy m.l.c.t. maxima in the electronic spectra also correlate with ligand properties. [Ru(bipy)(2)(Hbig)][PF6](2), which has a dissociable proton on the biguanide ligand, undergoes deprotonation in strongly basic conditions (pK(a) = 12.3 +/- 0.2), which results in a red-shift of the m.l.c.t. transition consistent with weakening of the ligand field due to the increased pi-donor capability of the deprotonated ligand.

  N-Substituted Hydroxylamines as Synthetically Versatile Amino Sources in the Iridium-Catalyzed Mild C–H Amidation Reaction

  摘要：

  N-Substituted hydroxylamines such as aroyloxy- or acyloxycarbamates were successfully employed as synthetically versatile amino precursors in the iridium-catalyzed direct C-H amidation of arenes. The reaction proceeds smoothly at room temperature over a broad range of substrates with high functional group tolerance to afford N-substituted arylamine products.

  Heteroaryl-substituted arenes and heteroarenes were efficiently amidated through ruthenium-catalyzed C–H bond functionalizations with a variety of sulfonyl azides. Particularly, cationic ruthenium(II) complexes proved to be most effective and allowed nitrogenations of electron-rich and electron-deficient arenes with ample substrate scope.

  reaction using organic azides as the amino source. The most important two stages were investigated especially in detail: (i) the formation of metal nitrenoid species and its subsequent insertion into a rhodacycle intermediate, and (ii) the regeneration of catalyst with concomitant release of products. It was revealed that a stepwise pathway involving a key Rh(V)-nitrenoid species that subsequently undergoes

  芳烃的直接 CH 胺化为苯胺化合物提供了一种直接的途径，而无需芳基（伪）卤化物作为起始材料。该领域的最新发展，特别是金属介导的转化，在底物范围和反应条件方面具有重要意义。本文描述了使用有机叠氮化物作为氨基源的 Rh 催化的直接 CH 胺化反应的机理细节。特别详细地研究了最重要的两个阶段：(i) 金属氮烯类物质的形成及其随后插入红环中间体，以及 (ii) 伴随产物释放的催化剂再生。结果表明，与协调的 CN 键形成途径相比，涉及随后经历酰胺插入的关键 Rh(V)-硝基化合物的逐步途径更受青睐。DFT 计算和动力学研究表明，当前 CH 胺化反应中的限速步骤与 Rh-nitrenoid 中间体的形成更密切相关，而不是预设的 CH 活化过程。本研究提供了直接 CH 胺化反应的机械细节，该反应具有催化循环内球内和外球路径的两个方面。

  We report the direct amidation of arene C-H bonds using sulfonyl azides as the amino source to release N(2) as the single byproduct. The reaction is catalyzed by a cationic rhodium complex under external oxidant-free conditions in the atmospheric environment. A broad range of chelate group-containing arenes are selectively amidated with excellent functional group tolerance, thus opening a new avenue
