摘要: Ionic liquids formed by imidazolium and pyridinium cations with Cl-, Br-, BF-4, and PF-6 anions were used for the catalytic synthesis of 2,3-dichloropropionitrile by the chlorination of acrylonitrile. The ionic liquids containing Cl- and Br- show good catalytic properties. The Cl- and Br- ions act as strong Lewis bases and molecular chlorine is activated by the induction effect of Cl- and Br-. Due to the stronger steric hindrance effect of the BF-4 and PF-6 anions, the chlorination of acrylonitrile is limited in the ionic liquids containing BF-4 and PF-6 anions.
