  Nickel-Catalyzed Suzuki–Miyaura Reaction of Aryl Fluorides

  摘要：

  Two protocols for the nickel-catalyzed cross-coupling of aryl fluorides with aryl boronic esters have been developed. The first employs metal fluoride cocatalysts, such as ZrF4 and TiF4, which enable Suzuki-Miyaura reactions of aryl fluorides bearing electron-withdrawing (ketones, esters, and CF3), aryl and alkenyl groups as well as those comprising fused aromatic rings, such as fluoronaphthalenes and fluoroquinolines. The second protocol employs aryl fluorides bearing ortho-directing groups, which facilitate the difficult C-F bond activation process via cyclometalation. N-heterocycles, such as pyridines, quinolines, pyrazoles, and oxazolines, can successfully promote cross-coupling with an array of organoboronic esters. A study into the substituent effects with respect to both coupling components has provided fundamental insights into the mechanism of the nickel-catalyzed cross-coupling of aryl fluorides.

  FI-750-M胶束中的π-烯丙基钯物种，用于水中未活化喹啉体系的可持续和一般的铃木-宫浦联轴器

  摘要：

  在环境友好的脯氨酸衍生表面活性剂FI-750-M的纳米胶束中使用π-烯丙基Pd催化剂已证明，2-，4-喹啉和异喹啉体系具有常规，清洁和可持续的Suzuki-Miyaura交叉偶联。优化的反应条件主要提供了高达克级的良好至优异的收率，高选择性和官能团耐受性。对照研究表明，该催化剂在FI‐750‐M中具有长期稳定性。催化剂和胶束反应介质均已再循环。纳米胶束的行为已通过DLS和冷冻TEM测量得以阐明，并且机理研究表明，喹啉氮与钯的可逆结合竞争性地抑制了反应速率。

  A nickel-catalyzed C–H cyanation reaction of arenes has been developed using 2-cyanoisothiazolidine 1,1-dioxide as an electrophilic cyanation reagent. Many different directing groups can be used in this cyanation to obtain a series of cyanation products with good yields. Adopting this strategy to introduce a cyano group, natural alkaloid menisporphine was successfully synthesized through cyano group

  hydro-defluorination and a ligand exchange reaction during the syntheses of neutral iridium(III) complexes is presented. Surprisingly, loss of one fluorine atom per ligand combined with a complete ligand exchange reaction on the transition metal were jointly observed during a bridge-splitting and substitution reaction of two different dimeric iridium(III) precursor complexes with two different ancillary ligands

  介绍了在中性铱（III）配合物合成过程中区域选择性加氢脱氟和配体交换反应的首次报道。令人惊奇地，在两个不同的二聚铱（III）前体配合物与两个不同的辅助配体的桥拆分和取代反应期间，共同观察到每个配体损失一个氟原子与在过渡金属上的完全配体交换反应相结合。在这两种情况下都证明了脱氟的区域选择性。反应时间被认为是强烈影响热诱导反应动力学的因素。

  derivatives with peresters in the presence of [Ru(p-cymene)Cl2]2 has been developed. The combination of ruthenium(II), AgBF4, CoI2, and 2,2,6,6-tetramethyl-1-piperidinyloxy is found to be an effective catalytic system to provide various biaryl compounds in satisfactory yields within minutes. Notably, steric hindrance is a very important determinant of the reaction.
