Cyclic chlorophosphites of ortho-bridged phenols are made by reaction of an ortho-bridged bisphenol with PCl₃ in an inert solvent using a catalytic amount of a polymeric compound having a pyridine skeletal structure and a cross-linked structure to promote the reaction.
原桥双酚的环状氯膦酸盐是通过原桥双酚与 PCl₃ 在惰性溶剂中反应制得的,使用催化剂量的具有吡啶骨架结构和交联结构的聚合化合物来促进反应。
