  Direct Prenylation of Aromatic and α,β-Unsaturated Carboxamides via Iridium-Catalyzed C−H Oxidative Addition−Allene Insertion

  摘要：

  Exposure of aromatic carboxamides 1e-1m, heteroaromatic carboxamides in-1p, and alpha,beta-unsaturated carboxamides 1q-1s to 1,1-dimethylallene in the presence of the a cationic iridium complex derived from [Ir(cod)(2)]BAr4F and rac-BINAP results in direct C-H prenylation to furnish adducts 2e-2m, 2n-2p, and 2q-2s, respectively, in good isolated yields as single isomers.

  One-Step RhCl₃-Catalyzed Deprotection of Acyclic N-Allyl Amides

  摘要：

  [GRAPHICS]A convenient one-step RhCl3-catalyzed deprotection of acyclic N-allyl amides is described. Preliminary mechanistic studies reveal that the key to the success of the one-step deprotection process is the dual function of RhCl3 in alcohol solvents. Reaction of RhCl3 with n-PrOH not only provides an active rhodium hydride species to catalyze isomerization of N-allyl amides to corresponding enamides but also generates a crucial catalytic amount of HCl to convert the enamides to deallylated amides through N,O-acetal exchange.

  mechanochemical synthesis of amides from carboxylic acids has been developed through an in situ acid activation with 2,4,6-trichloro-1,3,5-triazine and a catalytic amount of PPh3. Under room temperature solvent-drop grinding of the reactants in the presence of an inorganic base, a variety of carboxylic acids including aromatic acids, aliphatic acids, and N-protected α-amino acids undergo amidation to afford

  通过用2,4,6-三氯-1,3,5-三嗪和催化量的PPh 3进行原位酸活化，已经开发了从羧酸快速，简便而有效的机械化学合成酰胺的方法。在室温下，在无机碱的存在下，对反应物进行溶剂滴磨，使包括芳族酸，脂族酸和N-保护的α-氨基酸在内的各种羧酸酰胺化，以中等至极好的收率得到酰胺。该方法还与Fmoc，Cbz和Boc保护基兼容，可产生受保护的旋光二肽而没有可检测的消旋作用。

  evidenced by the catalytic reaction of cyclohexane with benzamide in the presence of CBr4, which formed exclusively bromocyclohexane. Furthermore, stoichiometric reactions of [(phen)Cu(phth)2] with tBuOOtBu and (Ph(Me)2CO)2 at 100 °C without cyclohexane afforded N-methylphthalimide (Me-phth) from β-Me scission of the alkoxy radicals to form a methyl radical.

  我们报道了一系列罕见的铜催化烷烃与简单酰胺、磺酰胺和酰亚胺（即苯甲酰胺、甲苯磺酰胺、氨基甲酸酯和邻苯二甲酰亚胺）的反应，形成相应的 N-烷基产物。这些反应导致仲 C-H 键官能化超过叔 C-H 键，甚至发生在伯 C-H 键上。 [(phen)Cu(phth)] (1-phth) 和 [(phen)Cu(phth)2] (1-phth2) 是反应中的潜在中间体，已被分离并充分表征。研究了 1-phth 和 1-phth2 与烷烃、烷基自由基和自由基探针的化学计量反应，以阐明酰胺化的机理。催化和化学计量反应需要铜和 tBuOOtBu 来生成 N-烷基产物。在没有 tBuOOtBu 的情况下，1-phth 和 1-phth2 在 100 °C 下均不会与过量环己烷反应。然而，1-phth 和 1-phth2 与 tBuOOtBu 的反应分别以大约 70:20:30 的比例提供 N-环己基邻苯二甲酰亚胺

  shows high activity in the successive cleavage of unactivated C(aryl)—O bonds of diaryl ethers and strong electrophilic Si—Cl bonds of chlorosilanes, allowing their cross-coupling in a reductive fashion. The low-valent iron species generated in situ by reduction of FeCl2 with iPrMgCl was proposed, which prefers to initially cleavage the C(aryl)—O bond of diaryl ethers with the chelation help of an o-amide

  C(芳基)-O和Si-Cl键之间的还原交叉偶联作为构建C(芳基)-Si键的有价值的策略非常重要，但仍然是一个巨大的挑战。在此，我们报道了二芳基醚和氯硅烷通过铁催化的强亲电子C(芳基)-O和Si-Cl键断裂进行还原交叉偶联，这构成了合成一系列官能化芳基硅烷的有效方案。低成本FeCl 2 作为预催化剂和PrMgCl作为还原剂的组合在二芳基醚未活化的C(芳基)-O键和氯硅烷的强亲电Si-Cl键的连续断裂中表现出高活性，允许它们以还原的方式交叉耦合。提出了用 PrMgCl 还原 FeCl 2 原位生成低价铁物种，该物种倾向于在邻酰胺的螯合帮助下首先裂解二芳基醚的 C(芳基)-O 键辅助的。
• The Scope and Limitation of Nickel-Catalyzed Aminocarbonylation of Aryl Bromides from Formamide Derivatives

  日期：2009.8.21

  Nickel-catalyzed aminocarbonylation of aryl halides is described. A well-defined air-stable nickel-phosphite catalytic system (Ni(OAc)(2)center dot 4H(2)O/phosphite 1) effectively promoted the aminocarbonylation of aryl bromides with a range of formamides to give the corresponding aryl amide products in moderate to good yields. The less hindered formamide required lower catalytic loading for full conversion and produced higher yields than the more hindered one. It also exhibited base-dependent activity toward formamides.
