Improvement Method for Synthesis of p-tert-butylthiacalix[n]arenes; Effect of Using Base Catalyst with Carboxylic Acid
The improved method for synthesis of p-tert-butylthiacalix[n]arenes (TCnAs) by using precursor which is sulfur-bridged oligomer of p-tert-butylphenol with acetic acid and terephthalic acid as a template in a combination with base catalyst such as NaOH and NaH gave much better yields for TC6A (10.6 %...

| Zusammenfassung: | The improved method for synthesis of p-tert-butylthiacalix[n]arenes (TCnAs) by using precursor which is sulfur-bridged oligomer of p-tert-butylphenol with acetic acid and terephthalic acid as a template in a combination with base catalyst such as NaOH and NaH gave much better yields for TC6A (10.6 %) and TC8A (7.8 %), respectively. Such stronger base NaH than NaOH could bring down a reaction temperature for synthesis of TC8A. |
