A method for carrying out a chemical reaction between at least two reactants occupying separate phases within a multiphase reaction mixture has been discovered in which at least one phosphazenium salt is employed as a phase transfer catalyst. The remarkable utility of phosphazenium salts as phase transfer catalysts is illustrated by the preparation of aromatic ethers. The phosphazenium salt phase transfer catalysts are shown to be especially useful in the preparation of aromatic polyethers such as polyether sulfones.
