  摘要：

  在受限介质（极端条件）下使用接触爆炸性伯胺和高价碘（III）（苯基碘二乙酸酯）进行任何合成转化几乎是不可能的。在这里，我们报告了一种使用酸盐NaHSO 4将爆炸控制成成功的化学反应的方法。作为概念验证，我们考虑了通过CH活化进行醛酰胺化的机械化学（球磨）交叉脱氢偶联（CDC）反应。等温滴定量热法（ITC）研究有助于理解在加入NaHSO 4之前和之后反应过程中的焓变。

  Transamidation reactions are often mediated by reactive substrates in the presence of overstoichiometric activating reagents and/or transition metal catalysts. Here we report the use of CO2 as a traceless catalyst: in the presence of catalytic amounts of CO2, transamidation reactions were accelerated with primary, secondary, and tertiary amide donors. Various amine nucleophiles including amino acid

  在过量化学计量的活化试剂和/或过渡金属催化剂的存在下，转酰胺基反应通常由反应性底物介导。在这里，我们报告了使用 CO 2作为无痕催化剂：在催化量的 CO 2存在下，使用伯、仲和叔酰胺供体加速转酰胺反应。包括氨基酸衍生物在内的各种胺类亲核试剂都被耐受，这表明转酰胺基在肽修饰和聚合物降解中的实用性（例如，Nylon-6,6）。特别是，N , O -二甲基羟基酰胺（Weinreb 酰胺）在 CO 2催化的转酰胺基反应中与 N 2相比表现出明显的反应性大气层。进行了比较 Hammett 研究和动力学分析，以阐明分子 CO 2的催化活化机制，这得到了 DFT 计算的支持。我们将CO 2在转酰胺基反应中的积极作用归因于通过与亲电子CO 2共价结合来稳定四面体中间体。

  Homoleptic lanthanide complex Y[N(TMS)2]3 is an efficient homogeneous catalyst for the hydroboration reduction of secondary amides and tertiary amides to corresponding amines. A series of amides containing different functional groups such as cyano, nitro, and vinyl groups were found to be well-tolerated. This transformation has also been nicely applied to the synthesis of indoles and piribedil. Detailed

  A simple method for the synthesis of amides has been developed by molybdenum-mediated carbamoylation of aryl halides. Whereas the conventional palladium-catalyzed three-component coupling reaction requires a large excess of gaseous carbon monoxide, the incorporation of carbon monoxide in this Mo-mediated carbamoylation reaction is so efficient that it requires only a slight excess amount of carbon monoxide
