以三价磷化合物为偶联剂，合成了6种有机电子给体，对偶联反应规律、应用范围及反应机理进行了讨论。提出该偶联反应的环加成与碳烯反应的竞争机制，认为反应中的重排是[2，3]负离子σ迁移反应。
Six kinds of organic electron donors were synthesized by using trivalent phosphorus compounds as coupling agent. The coupling reaction rules, application scope and reaction mechanism were discussed. The competition mechanism between the cycloaddition and the reaction of the carbene was proposed. The rearrangement in the reaction was considered as the [2,3] negative ion σ migration reaction.
