Anomalous NMR behavior of meso compounds with remote stereogenic centers on addition of chiral shift reagent or chiral solvating agent

Addition of chiral shift reagent (CSR) or chiral solvating agent (CRA) to separate meso and racemic forms of some diastereoisomeric single-bridged cyclophosphazene compounds causes doubling of 31P NMR signals for both isomers. The anomalous behavior on addition of CSR/CSA is only found for meso forms of cyclophosphazene compounds.
