Abstract

A rapid and efficient synthesis of nitriles via dehydration from the corresponding aldoximes has been carried out in the presence of ZnO/CH₃COCl as catalyst under solvent free conditions in 83-95% yields. The zinc oxide (ZnO) powder can be re-used upto three times after simple washing with CH₂Cl₂.
