H. Akdas et al., THIACALIXARENES - SYNTHESIS AND STRUCTURAL-ANALYSIS OF THIACALIX[LT]ARENE AND OF P-TERT-BUTYLTHIACALIX[4]ARENE, Tetrahedron letters, 39(16), 1998, pp. 2311-2314
The synthesis of tetrathiacalix[4]arene was achieved by the detertiobu
tylation of p-tert-butyltetrathiacalix[4]arene. X-ray diffraction stud
ies revealed that in the solid state whereas p-tert-butyltetrathiacali
x[4]arene forms inclusion complexes with solvent molecules, tetrathiac
alix[4]arene undergoes self-inclusion leading to trimeric units. The s
ame behaviour in the crystalline phase was also demonstrated for calix
[4]arene. (C) 1998 Published by Elsevier Science Ltd. All rights reser
