## Abstract Full NMR spectral assignments of the phospholene chalcogenides **1–12** are presented and their stereochemistry proven. The enantiomeric ratio of any of these compounds can be monitored easily by adding one mole equivalent of the chiral auxiliary Rh~2~[(__R__)‐MTPA]~4~ (MTPA‐H ≡ Mosher'
