| Abstract: | The formation of a stable calix4]arene monohemiketal is described. X-ray crystallographic data provide conclusive evidence for the presence of a stabilizing hydrogen bond. Supplementary Data. Lists of H-atom parameters and bond lengths and angles involving hydrogens have been deposited with the British Library Document Supply Centre as Supplementary Publication No. SUP 82159 (5 pp.). |
