چکیده

The selective nitrosation of β-dicarbonyl compounds with sodium nitrite was carried out under1-
methyl-3-carboxymethylimidazolium chloride, prepared from N-methylimidazole and
chloroacetic acid, as an acidic ionic liquid. The reaction was found to proceed under relatively
mild conditions with excellent conversion and selectivity. The ionic liquid was recycled and
reused.
