In the prolongation period of this research project, we want to continue with the comparative study of oxaphosphirane and epoxide chemistry, whereby transition metal-free routes shall be investigated in addition to the successful system Li/Cl-phosphinidenoid complex/carbonyl derivative. With respect to reactivity studies the work program is focused on the following three problems: decomplexation (A), carbenoid oxaphosphirane complexes (B), and ring-opening vs. ring-expansion reactions (C); B and C represent preliminary studies for polymerization reactions. In well established international collaborations, flame retardance testings shall be performed together with polymer analyses (with D.P. Gates/Canada), and reaction pathways elucidated via theoretical methods (with A. Espinosa Ferao/Spain). The latter will enable to describe structure reactivity relationships of oxaphosphiranes.

在本研究项目的延长期内，我们希望继续进行oxaphosphirane和环氧化物化学的比较研究，除成功的Li/Cl-膦酰亚胺络合物/羰基衍生物系统外，还应研究无过渡金属路线。关于反应性研究，工作计划集中在以下三个问题上：解络合（A）、类卡宾氧杂磷杂环己烷络合物（B）和开环与扩环反应（C）; B和C代表聚合反应的初步研究。在建立良好的国际合作中，阻燃性测试应与聚合物分析（与D. P. Gates/Canada合作）一起进行，并通过理论方法阐明反应途径（与A.埃斯皮诺萨Ferao/西班牙）。后者将能够描述氧杂磷杂环己烷的结构反应性关系。
