✦ Synopsis

of the following in a volume of 1 liter: naphthalene (150 g), 2,5-diphenyloxazole (8 g), 1,4-bis(4-methyl-5-phenyl-oxazol-2-yI)benzene (0.6 g), ethylene glycol (20 ml), 2-ethoxyethanol(lOO ml), and toluene to make 1 liter. The radioactivity was measured in the liquid scintillation counter with an 18% gain setting. Each vial was counted twice, and the data represent the average of two counts. Results are shown in Table I.

## Abstract The enantiomeric purities of disubstituted β‐lactams were determined by ^1^H and ^13^C NMR spectroscopy using tris[3‐(trifluoromethylhydroxymethylene)‐d‐camphorato]europium(III), Eu(tfc)~3~, as a chiral shift reagent. Using a [Eu(tfc)~3~]/[lactam] ratio of 0.5, most of the resonances we

The 13C NMR behaviour of ten acyclic terpene alcohols was examined in the presence of a chiral lanthanide shift reagent (CLSR). For each alcohol, we measured the lanthanide-induced shift (LIS) on the signals of the carbons and the splitting of some signals, which allowed the enantiomeric differentia

## Abstract The dirhodium method has been successfully applied in chiral recognition of the optically active Schiff bases, derivatives of __ortho__‐hydroxyaldehydes existing in the NH‐form. or at tautomeric equilibrium. The position of the equilibrium of Schiff bases as well as their adducts has be
