converted to the corresponding phosphole oxides that, by the Diels–Alder reaction with N-maleimide derivatives or with another unit of phosphole oxide, yielded trapped phosphole oxides or phosphole oxide dimers, respectively, as new 7-phosphanorbornene 7-oxides. The stereostructures of three derivatives were evaluated by single crystal X-ray analysis. The regio- and stereospecific dimerization was studied
