## 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'

## Abstract Adducts of four phosphine chalcogenides with the chiral dirhodium complex ([RhRh]) were investigated by variable‐temperature ^1^H and ^31^P NMR spectroscopy in order to compare their properties as axial ligands. Whereas the selenide (1) and the sulfide (2) are strong ligands with elect
