Abstract: We have studied intramolecular hydrogen bonding in a homologous series of diamides (compounds 1-6) in methylene chloride, 9: 1 carbon tetrachloride/benzene, and acetonitrile. By correlating variable-temperature 'H NMR and 1R measurements, we have shown that the temperature dependence of the amide proton NMR chemical shift (Ab/AT) can provide qualitative (and in some cases quantitative) information on the ...
