N-acetylglyoxylic amides 4 and 5 bearing pendant 4-nitrophenyl and 2,4-dinitrophenyl groups respectively were synthesized and evaluated as anion sensors. A crystal structure of 4 was obtained by X-ray crystallography. Compounds 4 and 5 behaved as colorimetric sensors for CN- and F -, and exhibited naked eye-detectable color changes upon the addition of these anions. The chromogenic properties of 4 and 5 were assessed by UV-Vis and 1H NMR spectroscopy.
