Oxidation of' 3,4-dimethyl-l-phenylphosphole with peracids or peroxides gives a relatively stable P-oxide, which can be used in Diels-Alder reactions to give derivatives with the 7-phosphanorbornene framework. Oxygen insertion into a C-P bond of this framework occurs smoothly with m-chloroperbenzoic
