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.
