  经由亚砜-镁交换反应的芳烃的间-和对-双官能化。

  摘要：

  芳基亚砜部分（ArSO）可以方便地进行易得的二芳基亚砜的两步间，对二官能化。在第一步中，亚砜起着直接金属化基团的作用。在第二步中，由i-PrMgCl x LiCl触发，它成为一个离去基团，并进行区域选择性的亚砜-镁交换。

• Two-Step Synthesis of Unsymmetrical Diaryl Sulfides by Electrophilic Thiolation of Non-functionalized (Hetero)arenes
  作者：Marvin J. Böhm、Christopher Golz、Isabelle Rüter、Manuel Alcarazo

  日期：2018.10.9

  article reports the efficient preparation of a series of unsymmetrically substituted thioethers through a two‐step procedure consisting of an initial metal‐free C−H sulfenylation of electron‐rich (hetero)arenes with newly prepared succinylthioimidazolium salts. Subsequent reaction of the arylthioimidazolium intermediates with Grignard reagents afford the desired thioethers. The synthetic protocol described

  本文报道了通过两步程序有效地制备一系列不对称取代的硫醚的方法，该程序包括用新制备的琥珀酰硫代咪唑鎓盐对富电子（杂）芳烃进行初始无金属CH磺酰化反应。芳基硫代咪唑鎓中间体与格利雅试剂的随后反应得到所需的硫醚。所描述的合成协议是模块化的，可伸缩的且产率高，并且提供了通过现有方法不易获得的硫化物的途径。重要的是，不需要初始（杂）芳烃的预官能化。
• Phosphorothioic Acids and Related Compounds as Surrogates for H₂S—Synthesis of Chiral Tetrahydrothiophenes

  The convenient preparation of chiral tetrahydrothiophenes (THTs) in high enantiopurity via phosphorothioic acids and related compounds is reported. We consider these to be safer alternatives to the use of H(2)S which is a highly toxic gas. Each of the THTs is derived from a common intermediate, thereby greatly enhancing the flexibility of the synthesis. The key transformation is a base-promoted, intramolecular

  报道了通过硫代磷酸和相关化合物方便地制备高对映纯度的手性四氢噻吩 (THT)。我们认为这些是使用 H(2)S（一种剧毒气体）的更安全替代品。每个THTs都来源于一个共同的中间体，从而大大提高了合成的灵活性。关键的转化是碱基促进的、分子内的、碳-硫键形成事件。这些反应是高度立体定向的，因为它们通过双 S(N)2 置换机制进行操作。该方法适用于广泛的官能团和杂环。四氢噻吩基序很重要，因为它存在于许多生物活性天然产物中。它们还被用于促进各种不对称转化，包括氢化、环氧化、

  Highly functionalized 1,2,4-trisubstituted arenes can be prepared on large scale by a two-step sequence, triggered by an aryl sulfoxide­ group. In the first step, the sulfoxide moiety acts as a metalation directing group, allowing a smooth magnesiation with tmpMgCl˙LiCl. After a quenching reaction with an electrophile, the resulting sulfoxide is converted with i-PrMgCl˙LiCl into a second magnesium

  高度官能化的1,2,4-三取代的芳烃可以由芳基亚砜基团触发的两步顺序大规模制备。在第一步中，亚砜部分充当金属化导向基团，允许用tmpMgCl 3 LiCl平滑地放大。与亲电试剂猝灭后，生成的亚砜被i -PrMgCl 3 LiCl转化为第二种镁试剂（亚砜-镁交换），可以被各种亲电试剂捕获。具有高度化学选择性的tmpMgCl 3 LiCl和i -PrMgCl 3 LiCl与多种官能团（FG = F，Cl，CF 3，CN，CO 2 t- Bu，炔基）兼容。 金属化-邻位镁化-亚砜-镁交换-多官能格氏试剂
• Hydroxylated terphenylphosphine ligands for palladium-catalyzed ortho-selective cross-coupling of dibromophenols, dibromoanilines, and their congeners with Grignard reagents
  作者：Shunpei Ishikawa、Kei Manabe

  日期：2011.12

  p-Terphenylphosphines bearing one or two hydroxy groups were used as ligands to palladium in the cross-coupling of dibromophenols, dibromoanilines, and their congeners with Grignard reagents. High ortho-selectivity that cannot be achieved using other phosphine ligands was observed. ortho-Preference was also observed in competitive cross-coupling reactions of two substrates. A significant effect of the concentration of the Grignard reagent on the ortho-selectivity was observed, when the hydroxylated terphenylphosphines were used. Kinetic studies on this effect showed that high concentrations of the Grignard reagent retard the cross-coupling reaction only at the para-position, but not at the ortho-position.
