Solvent-free synthesis of (poly)thiacalix[n]arenes: the evaluation of possible mechanism based on semi-preparative HPLC separation and mass-spectrometric investigation of the reaction products

Abstract

The interaction between p-tert-butylphenol and elemental sulfur (S8) in alkaline condition in absence of solvent at 150-170 °C have been studied. (Poly)thiacalix[n]arenes with the phenol units connected by bi-and trisulfide bridges have been detected and characterized based on the MS data.
