Abstract
The addition of Eu(DPM)3 to phosphoryl-bearing molecules produces striking spectral simplification by virtue of strong and almost complete complexing of the PO group. The chemical shift induced by this complexing is dependent on the distance between the particular hydrogen shifted, by the complex, and the complexed site. In various molecules containing both PO and other lone pair electron sites, complexing was found to be greater at the PO, and only once this site was fully complexed, the other moieties underwent considerable complexing.
