Reactions of resorcinarene with N,N-dimethylcarbamoyl and N,N-dimethylthiocarbamoyl chlorides. Factors affecting the process performance

Abstract

Carbamoylation and thiocarbamoylation of resorcinarenes in the presence of alkali metal carbonates were studied. The effects of the pre-organization of the resorcinarene molecule, the base used, and the nature of the acylating reagent on the reaction outcome were demonstrated. It was shown that octacarbamoylated resorcinarenes in the boat conformation show high absorption properties and selectivity towards cesium cations.
