Abstract
Phosphorylation of calix[4]resorcinolarenes with PCl3 yields cyclic phospho rochloridites. Cavitands containing cyclic phosphorochloridite fragments in the upper rim are readily oxidized with SO2Cl2 to the corresponding phosph orochloridates and take up four equivalents of sulfur on heating to form cy clic phosphorochloridothioates.
