Abstract
Octa-functionalizations of C-heptyl- and C-undecylcalix (4) resorcinarenes were obtained by substitution reactions with $\alpha$-bromoacetates or $\alpha$-bromoacetamides. The association constants of cation binding of 3 a-c and 4 a-c were determined using alkali cations, (Na$\sp+$, K$\sp+$, Rb$\sp+$, Cs$\sp+$), alkaline earth cations, (Mg$\sp{2+},$ Ca$\sp{2+},$ Ba$\sp{2+}$), ammonium ions, (NH$\sb4\sp+,$ t-BuNH$\sb3\sp+$), silver(I) and lanthanum(III) cations by means of the picrate extraction technique via UV-VIS spectroscopy. The conformations of 3c and 3c $\cdot$ Ag$\sp+$ were determined to be flattened cone by variable temperature $\sp1$H NMR studies. Source: Masters Abstracts International, Volume: 34-02, page: 0764.
