Synthesis of a series of novel tetra-tert-butylcalix[4]arene linked to 1,2,4-triazole and 1,3,4-oxadiazole derivatives

Abstract

A series of tetra-tert-butylcalix[4]arene linked to 1,2,4-triazole-5-thiones and 1,3,4-oxadiazole-5-thiones derivatives at lower rim were synthesized by the reaction of 1,2,4-triazole-5-thione and 1,3,4-oxadiazole-5-thione  with 5,11,17,23-tetra-tert-butyl-25,27-bis(3-bromo propoxy)-26,28-dihydroxycalix[4]arene (2). The synthesized compounds were characterized by FT-IR, ¹H NMR, ¹³C NMR spectral data, elemental analysis and ESI-MS.
