R. Lamartine et al., Synthesis, X-ray crystal structure and complexation properties towards metal ions of new thiacalix[4]arenes, TETRAHEDR L, 42(6), 2001, pp. 1021-1024
p-tert-Butyl-tetrakis[(methylcarbonyl)methoxy]tetrathiacalix[4]arene and p-
tert-butyl-tetrakis[(benzoyl)methoxy]tetra-thiacalix[4]arene were prepared
and their conformation was established by X-ray crystallography, p-tert-But
yl-tetrakis-[(diethylamide)methoxy]tetrathiacalix[4]arene was also synthesi
zed. The ability of these three macrocycles to bind metal ions was investig
ated via a solvent extraction study. (C) 2001 Elsevier Science Ltd. All rig
