The reaction of diethyl bromomalonate with p-tert-butylthia-calix[4]arene: an approach to asymmetrical derivatives

Molecules. 2009 May 7;14(5):1755-61. doi: 10.3390/molecules14051755.

Abstract

New dissymmetric and asymmetric p-tert-butylthiacalix[4]arene derivatives were prepared as a result of the reaction of p-tert-butylthiacalix[4]arene with diethyl bromomalonate in the presence of different alkali metals (Cs, K and Na) in refluxing acetone for 7 days. The structures of the prepared compounds were investigated by IR, (1)H-NMR and MALDI-TOF mass spectroscopy.
