We have recently reported a new class of macrocycle, the thiacalixthianthrenes. This paper describes some attempts to modify thiacalixthianthrene and a study of the structure of oxidized derivatives.
[EN] The invention relates to compounds of formula (I), wherein X1 to X6, n1 to n4 and R1 to R4 are as defined in claim 1, and to the radicals and metallic complexes of these compounds. [FR] La présente invention a pour objet les composés de formule (I) : dans laquelle X1 à X6, n1 à n4 et R1 à R4 sont tels que définis à la revendication 1, ainsi que les radicaux et complexes métalliques de ces composés.

New thianthrene based macrocycles with basket shaped structures were prepared by thermal treatment of tetrakis-(N,N′-dimethylthiocarbamoyl)-tetra-tert-butyl-thiacalix[4]arene. Their structural characterization as well as the study of the formation mechanisms are presented in this article. The influence of the conformation of the starting thiacalixarene on the reaction is also discussed.
