摘要:
The preparation of N,N'-diarylalkanediamides from the respective aliphatic dicarboxylic acids and 4-nitroaniline via microwave-prompted reactions is presented. The most positive effect of microwave irradiation was observed for N,N'-bis(4-nitrophenyl)butanediamide. Anion binding studies on the obtained diamides were carried out in DMSO and acetonitrile using UV-vis and H-1 NMR spectroscopy. A mechanism for selective fluoride recognition by N,N'-bis(4-nitrophenyl)butanediamide in DMSO is proposed. (C) 2012 Elsevier Ltd. All rights reserved.
