| Abstract: | Previous work in these laboratories1 and elsewhere2,3 has pointed to the value of a mixture of lanthanide fod chelates with silver fod1,2 or with silver trifluoroacetate3 in simplifying the 1H NMR spectra of aryl substrates which do not possess the conventional (O or N) donor groups (fod = 2,2-dimethyl-6,6,7,7,8,8,8-heptafluoro-3,5-octane dionate). |
