羧酸与四碘化二磷和碳酸铵在无水二硫化碳中室温反应5～9h,得到相应的腈。羧酸分子中若含有手性碳、酯基、醚基等均不受影响。17例收率80%～92%。
The carboxylic acid is reacted with phosphorus tetraiodide and ammonium carbonate in anhydrous carbon disulfide for 5 to 9 hours at room temperature to obtain the corresponding nitrile. Carboxylic acid molecules containing chiral carbon, ester, ether and so on are not affected. 17 cases of 80% to 92% yield.
