The synthesis of tetrathiacalix [4]arene was achieved by the detertiobutylation of p-tert-butyltetrathiacalix[4]arene. X-ray diffraction studies revealed that in the solid state whereas p-tert-butyltetrathiacalix[4]arene forms inclusion complexes with solvent molecules, tetrathiacalix[4]arene under

A series of alkyl substituted thiacalix [4]arene derivatives (being conformationally mobile or immobilised in the cone conformation) was used as the starting point for this study. It was demonstrated that the NaNO 3 /CF 3 COOH system can serve as an excellent oxidising agent. The oxidation of the br
