A convenient and efficient one-pot preparation of nitriles from alcohols using N-(p-toluenesulfonyl)imidazole (TsIm) is described. In this method, treatment of alcohols with a mixture of NaCN, TsIm and triethylamine in the presence of catalytic amounts of tetra-n-butylammonium iodide (TBAI) in refluxing DMF furnishes the corresponding alkyl nitriles in good yields. This methodology is highly efficient
描述了使用N-(对甲苯磺酰基)咪唑(TsIm)从醇中方便,有效地一锅制备腈的方法。在这种方法中,在回流的DMF中,在催化量的碘化四正丁基碘铵(TBAI)存在下,用NaCN,TsIm和三乙胺的混合物处理醇,可得到相应的烷基腈,收率很高。该方法对于各种结构多样的醇具有很高的效率,并且对ROH的选择性为:1°> 2°> 3°。
