Abstract
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.
