  methods to prepare aryl nitriles and vinyl nitriles from aryl halides and alkynes, respectively. Using inexpensive and non-toxic 4-cyanopyridine N-oxide as the cyano shuttle, the methods provide an efficient approach to prepare aryl cyanides and vinyl nitriles under mild and operationally simple reaction conditions with a broad range of functional group tolerance. In hydrocyanation of alkynes, the method

  我们报告镍催化氰化和氢氰化方法分别从芳基卤化物和炔烃制备芳基腈和乙烯基腈。使用廉价且无毒的4-氰基吡啶N-氧化物作为氰基梭，该方法提供了一种在温和且操作简单的反应条件下制备具有宽泛官能团耐受性的芳基氰化物和乙烯基腈的有效方法。在炔烃的氢氰化中，该方法表现出良好的区域选择性，可控方式主要产生E或Z烯基腈，而分别以内部二芳基炔烃和末端炔烃为底物时，则仅产生马尔可夫尼科夫乙烯基腈。

  efficient protocol was developed for the synthesis of carboxylic acids, esters, and amides through oxidation of alkynyl boronates, generated directly from terminal alkynes. This protocol represents the first example of C(sp)−B bond oxidation. This approach displays a broad substrate scope, including aryl and alkyl alkynes, and exhibits excellent functional group tolerance. Water, primary and secondary

• Transformation of Carbonyl Compounds into Homologous Alkynes under Neutral Conditions: Fragmentation of Tetrazoles Derived from Cyanophosphates
  作者：Hiroki Yoneyama、Masahiro Numata、Kenji Uemura、Yoshihide Usami、Shinya Harusawa

  Cyanophosphates (CPs) can be easily prepared from either ketones or aldehydes, and their reaction with NaN3–Et3N·HCl results in the formation of azidotetrazoles. Under microwave irradiation, successive fragmentation of the azidotetrazoles generates alkylidene carbenes that undergo [1,2]-rearrangement and are transformed into homologous alkynes. Treatment of ketone-derived CPs with TMSN3 and Bu2SnO

  氰基磷酸盐（CPs）可以很容易地从酮或醛中制备，它们与NaN 3 -Et 3 N·HCl的反应导致叠氮四唑的形成。在微波辐射下，叠氮四唑的连续断裂产生亚烷基卡宾，经过[1,2]重排并转化为同源炔烃。用TMSN 3和Bu 2 SnO作为催化剂在甲苯中回流处理酮衍生的CP，可直接产生相应的内部炔烃，而醛衍生的CP与NaN 3 -Et 3 N·HCl在THF中的回流或TMSN 3反应–Bu 2回流中的甲苯中的SnO（催化）可提供高收率的同源末端炔烃。这些反应在中性条件下进行，可以成功地扩展以得到通常需要通过碱性条件的Ohira–Bestmann或Shioiri方法从相应的羰基化合物无法获得的炔烃。
