Selective phosphorylation of p-tert-butylcalix[6]arene

Abstract

The synthesis of selectively phosphorylated and thiophosphorylated p-tert-butylcalix[6] arenes is described; the solid-state structure of the 1,4-bis(thiophosphorylated)p-tert-butylcalix[6]arene is elucidated by X-ray crystallography.
