Experimental study demonstrates efficient synthesis of N-alkyl- and N-arylimides using choline chloride·2ZnCl2, indicating a mild and sustainable catalytic medium for imide preparation.
Lewis acidic ionic liquid choline chloride·2ZnCl2 is shown to be for the first time an excellent medium and efficient catalyst for the synthesis of N‐alkyl‐ and N‐arylimides in good yields under mild conditions.
