Extraction of platinum from aqueous solution into chloroform using a 2-pyridylthio- N-oxide derivatized calix[4]arene as phase transfer reagent

The compound 25,26,27,28-(2-(2-pyridylthio- N-oxide)ethoxy)calix[4]arene has been synthesized from 25,26,27,28-(2-bromoethoxy)calix[4]arene by reaction with 2-pyridylthiol- N-oxide in the presence of pyridine as base. The compound is one of the better modified calix[4]arene extractants for Pt(IV).
