| Abstract: | Lanthanide shift reagents can bring about dramatic simplifications of highly complex NMR spectra1,2. The applicability of the commonest of these (the thd and fod chelates of Eu, Pr and Yb) has been restricted to those molecules possessing a suitable N, O or S donor atom, although they may turn up in unusual guises, e.g. in quaternary ammonium compounds3. |
