磷杂环戊二烯在探索磷化学的研究中发挥了重要的作用,并广泛应用于配位化学、催化和有机光电材料等领域.[1,5]-σ键迁移(以下简称[1,5]迁移)是磷杂环戊二烯的一类重要反应.该迁移主要是由于磷杂环戊二烯弱的芳香性和环外磷上取代基的σ键与环内二烯体的反键轨道存在一定的σ-π*超共轭效应等特性所共同造成的.该反应自发现以来就成为磷杂环戊二烯衍生化的重要和有效手段.主要介绍了近几年来人们利用磷杂环戊二烯[1,5]迁移特性设计与合成新型有机磷化合物和含磷光电材料的研究进展.
Phosphacyclopentadienes play an important role in the exploration of phosphorus chemistry and are widely used in the field of coordination chemistry, catalysis and organic optoelectronic materials. [1,5] -σ bond migration (hereinafter referred to as [1, 5] migration) is a class of important reactions of phospholenes.The migration is mainly due to the weak aromaticity of the phospholenes and the σ bonds of the substituents on the exocyclic phosphorus to the Key orbitals have certain σ-π * superconjugation effect and other characteristics of the common cause of the reaction since the discovery has become an important and effective means of derivatization of phospholene mainly introduced in recent years, people use phosphorus Heterocyclopentadienes [1, 5] Migration characteristics of the design and synthesis of new organophosphorus compounds and phosphorescent materials research progress.
