## Abstract The NMR. spectra of a serie of β‐hydroxyesters have been studied. It has been found that the methylene protons are magnetically nonequivalent only when the substituents on the center of asymmetry of I or II are very different. The magnetically non‐equivalence of the isopropylmethylproto

## Abstract The spectrophotometric determination of traces of Ce^4+^ and Ti^3+^ in the presence of respectively large excesses of Ce^3+^ (≤ 10^–1^ M) and Ti^4+^ (≤ 10^−1^ M), is described. Indirect methods are elaborated for both ions. The reaction of Ce^4+^ with an excess of Fe^2+^ gives an equiv
Benzoyl chloride and AlC1~3~ give an addition compound with a dative oxygenaluminium bond. The FRIEDEL‐CRAFTS synthesis of benzophenone from benzoyl chloride and benzene in the presence of Al^36^C1~3~ is shown by the authors to give rise to a statistical repartition of the radioactive chlorine betwe
