| Outline of Final Research Achievements |
Organophosphorus compounds based on 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide derivatives have attracted much attention as environmental benign flame retardants. Various 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide derivatives were efficiently synthesized by Friedel-Crafts reaction of 2-hydroxybiphenyls with phosphorus trichloride in the presence of super acids, especially TfOH as a catalyst. The novel organophosphorus compounds consist of an ether bridge connecting with glutaryl dichloride and sebacoyl chlorides were synthesized. These compounds was determined and characterized by 1H-, 13C- 31P-NMR and TG-DTA data. It was found that the bridged organophosphorus compounds exhibited good thermal stability compared to the 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. This observation is important for high temperature polymer application requiring for the melt processing conditions.
