Chiral phospholene and phospholane chalcogenides: Stereochemistry and chiral recognition by multinuclear NMR spectroscopy of their Rh 2 [( R )‐MTPA] 4 adducts
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's acid) and sub...
