Abstract
tert-Butylcalix(n)arenes react with an excess of (iso)nicotinoyl chloride, yielding selectively n-2 acyl- ated products, calix(n)-(nico)n2(OH)2, (calix = 4-tert-butylcalix(n)arene; n = 4, 6, and 8; nico = (iso)nicoti- noylate) of alternate conformations. Their structures were determined by X-ray single crystallography and NMR spectra. The UV-vis spectra indicated that a new absorption band of the complexes appears upon the addition of cobalt(II) dichloride, and its crystal structure was resolved.
