  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。

  were successfully synthesized for the transesterification of DMC with BPA. The products of mono-methylcarbonate-ended-BPA (MmC(1)) and two-methylcarbonate-ended-BPA (DmC(1)) were selectively synthesized over them. The catalysts were characterized by FT-IR, TG and XPS. When Ph2SnO was used as the catalyst at 170 °C, the BPA conversion reached to 28.60% and the transesterification selectivity reached

  成功地合成了（CF 3 C 6 H 4）2 SnO，（CH 3 C 6 H 4）2 SnO和Ph 2 SnO用于DMC与BPA的酯交换反应。在其上选择性地合成了单碳酸酯封端的BPA（MmC（1））和两碳酸酯封端的BPA（DMC（1））的产物。通过FT-IR，TG和XPS对催化剂进行了表征。当在170°C下使用Ph 2 SnO作为催化剂时，BPA转化率达到28.60％，酯交换选择性达到98.35％。至于（CF 3 C 6 H 4）2SnO，BPA转化率和酯交换选择性分别降至12.48％和64.74％。与（CF 3 C 6 H 4）2 SnO相比，BPA转化率增加到42.83％，但酯交换选择性下降到44.55％。值得注意的是，Ph 2 SnO的较高的酯交换选择性是由于其最低的Sn 4+电子结合能。更重要的是，DMC在（CF 3 C 6 H 4）2 SnO，（CH 3 C 6 H 4）2 SnO和Ph
