  日期：2017.8.4

  A Co(II)-catalyzed isocyanide insertion reaction with sulfonyl azides in alcohols to form sulfonyl isoureas via nitrene intermediate has been developed. This protocol provides a new, environmentally friendly, and simple strategy for the synthesis of sulfonyl isourea derivatives by employing a range of substrates under mild conditions.

  日期：2018.9.18

  The newly discovered gold‐catalysed reaction of isocyanides with hydrazoic acid generated in situ from trimethylsilyl azide and methanol (or, alternatively, from NaN3/AcOH) produces either cyanamides or 1‐substituted 1H‐tetrazol‐5‐amines, depending on the amount of available HN3. The reaction proceeds selectively and in generally high yields of either product, thus providing a particularly convenient

  Eleven different gold(I) complexes of new NHC ligands were prepared in excellent yield, demonstrating the versatility of the new route to NHC complexes. While the influence of electronically different ligands on the synthesis of the catalysts was small, the catalytic activities of the products differed significantly.

  blocks, via C−H fluorination or via selective activation of perfluorinated compounds to give the partially fluorinated congeners. Especially the direct activation of C−F bonds, one of the strongest σ‐bonds, still remains challenging and new strategies for C−F activation are desirable. Herein a method for the photochemical activation of aromatic C−F bonds is presented. It is shown that isonitriles selectively

  氟化化合物已在农业化学工业，药物化学和材料科学领域中变得重要。因此，过去已经开发了各种制备方法。氟化化合物可通过与氟化结构单元共轭，CH氟化或通过全氟化合物的选择性活化而获得部分氟化同源物。尤其是C-F键（最强的σ键）之一的直接激活仍然具有挑战性，因此需要新的C-F激活策略。在此提出了一种光化学活化芳族CF键的方法。结果表明，异腈选择性地插入芳族CF键中，而脂族CF键不受影响。机理研究表明，该反应是通过在350 nm处由光激发的苯乙酮将异腈间接激发至三重态而进行的。由于所使用的光线相对温和，因此该方法显示出较高的官能团耐受性，并且苯甲酰亚胺基氟化物类的各种化合物可从芳基异腈和市售的全氟化芳烃中获得。

  The effect of the solvent on the diastereoselectivity of the Joullié–Ugi three-component reaction (JU-3CR) using an α-substituted five-membered cyclic imine is revisited. The cis and trans isomers were generated in toluene and HFIP, respectively. Hammett analysis of the JU-3CR suggests the presence of two reaction mechanisms.
