摘要:
The O-17 NMR shifts of diastereotopic sulfonyl oxygens within a series of conformationally homogeneous six-membered-ring organosulfur compounds have been determined. Their lanthanide-induced shifts (LIS), resulting from competitive complexation with the europium metal ion (i.e., Eu(fod)3), provide structural insights into the relative binding potential of the attached diastereotopic sulfonyl oxygens.
