摘要

To study the structures and reactivities of alkali metallated intermediates of calix[4]arenes, three compounds were isolated: [Li_4(p-tert-butylcalix[4]arene-4H)(thf)_4]_2·6THF (1), [Li_2(p-tert-butylcalix[4]arene-2H)(H_2O)(mu-H_2O)(thf)]·3THF (2), and [K_4(p-tert-butylcalix[4]arene-4H)(thf)_5]_2·THF (3). The structure of 1 is shown to be dependent on the coordinating solvent. Partial hydrolysis of 1 leads to the formation of 2. The potassium compound 3 features a different structure to that of 1, due to a higher coordination numbers as well as stronger cation-pi-bonding interactions.
