  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.

  已经发现了一种在多相反应混合物中进行至少两种占据不同相位的反应物之间的化学反应的方法，其中至少一种磷氮盐被用作相转移催化剂。磷氮盐作为相转移催化剂的显著实用性可通过芳香醚的制备来说明。磷氮盐相转移催化剂在芳香聚醚如聚醚砜的制备中被证明特别有用。
