摘要

A number of isopropyl-β-ketosulphinyl chlorides has been synthesised and their PMR spectra studied. Magnetic non-equivalence of the alpha gem-dimethyl groups is, in general, observed together with, in certain cases, magnetic non-equivalence of suitably positioned methylene and methine H atoms. This effect has been found to be temperature and solvent dependent and is probably due to both the intrinsic diastereomerism of the groups and to ...
