摘要

Ionic liquids based on 1-butyl-3-methylimidazolium tetrafluoroborate (BmimBF₄) and 1-butyl-3-methylimidazolium hexafluorophosphate (BmimPF₆) were used as reusable alternatives to volatile organic solvents (VOCs) for ethylenediammonium diacetate (EDDA) catalyzed Gewald synthesis of 2-aminothiophenes. Significant rate enhancement and improvement of the yield were observed. The ionic liquids containing catalyst EDDA were recycled several times with no decreases in yields and reaction rates.
