Abstract: The formation of mono- and di (1,2 and 1,3)-amide derivatives of <i>p-tert</i>-butylcalix[4]arene in the presence of sodium hydride has been demonstrated.  All the compounds have been purified and characterized by various spectral methods.  Both <sup>1</sup>H and <sup>13</sup>C NMR spectra exhibit clear-cut differences between the 1,2-di- and 1,3-di-amide derivatives.
