New phosphorus‐ and selenium‐containing heterocycles, 1,3,2,6‐dioxaphosphaselenacyclooctanes (1a—1h), were synthesized by the reaction of bis(2‐hydroxyethyl)selenide with RP(X)Cl 2 whore R=alkoxyl, aroxyl, aryl and X=O or lone pair. Their structures were determined by spectroscopies and elemental analyses and finally confirmed by the X‐ray crystallographic analysis of 1c. The molecular structures of the heterocycles were discussed in term of conformational analysis.
