三配位五价磷化学

TRICOODINATED PENTAVALENT ( σ 3 λ 5) PHOSPHORUS CHEMISTRY

对具有Ｒ－Ｐ（＝Ｘ）（＝Ｙ）结构的三配位五价磷化合物的结构特点、成键及光谱性质、合成方法及化学反应性能作了一描述．比较详细地讨论了以二配位磷化合物、三配位三价磷化合物以及四配位五价磷化合物为原料的合成方法。

In this review the structure characteristic,bonding and spectral properties,synthetic methods and chemical reactivity of tricoordinated pentavalent phosphorus Compound with the structure [R-P(=X)(=Y)] are described.The preparation routes from dicoordinated phosphorus compounds, tricoordinated tricovalent phosphorus compounds and tetracoordinated pentavalent phosphorus compounds are discussed in details.We mainly discuss eletrophilic properties of title compounds with nucleophilic reagents and cycloaddition reaction with unsaturated compounds.
