Phosphorylation of p-tert-butyl(thia)calixarenes by ethylene chlorophosphite

Abstract

The one-step synthesis of a macrocyclic node was performed by the interaction of thiacalix[4]arene with ethylene chlorophosphite; new cyclic derivatives of calix[n]arenes containing phosphorus fragments at the lower rim in the 1,2- (n=4) and 1,2,3-alternate (n=6) configurations were obtained. © 2012 Mendeleev Communications.
