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。
