Abstract
The ^17^O NMR diastereotopicity or chemical shift differences of diastereotopic sulfonyl oxygens in a series of trans‐2‐[alkyl(aryl)sulfonyl]cyclohexanols have been determined. From a comparison of their sulfonyl oxygen ^17^O NMR lanthanide‐induced shifts, equilibrium distributions between diastereomeric sulfonyl oxygen‐Eu(fod)~3~ complexes were determined and found to be sensitive to both the steric size of the –SO~2~R substituent as well as the proximity of the C1 hydroxyl group.
