Praseodymium(II1) tris(dipiva1omethanato) [Pr(DPM),] reduces the complex overlapping aromatic absorptions in the proton NMR spectrum of a monosubstituted naphthalene, cis-3-(1- naphthyl)-l,3,5,5-tetramethylcyclohexan-l-ol(l) to a virtually first-order pattern, whereas Eu(DPM), at the same and higher
## Abstract 2βAzetidinones which carry a proton each on Cβ3 and Cβ4 often pose a problem in the correct assignment of the resonances due to these protons; titanium tetrachloride has been shown to be an effective and reliable n.m.r. shift reagent to differentiate between these two protons on the bas
