Abstract
A simple efficient method for the synthesis of novel amides of phenyl-1, 4-dioxyacetic acid as molecular tweezers under solvent-free conditions and microwave irradiation has been developed. Its main advantages are short reaction times, good conversions and the environmentally friendly nature of the process. The structures of the products were confirmed by IR, 1H NMR, MS spectra and elemental analyses and their binding properties were examined by UV-vis spectral titration. Preliminary results indicated that these molecular tweezers show good selectivity for neutral organic molecules.
