✦ Synopsis


Twenty five cyclic and α‐cyclic thioketones were examined by mass spectrometry. Compared with the oxygen analogues, the thioketones yielded a higher proportion of molecular ions. The loss of •SH was found to be a characteristic fragmentation of cyclic and α‐cyclic thioketones as for aliphatic thioketones.

An examination of the mass spectra of aliphatic thioketones at 70 eV has shown some differences between these compounds and the corresponding ketones: the molecular ions of the thioketones were stronger than those of the ketones, indicating the greater ability of the sulfur atom to stabilise the rad

## Abstract Les spectres de RMN du carbone‐13 de diverses cétones et thiocétones aliphatiques ont été déterminés et expliqués. Le groupe thiocarbonyle est plus sensible à l'effet inducteur des groupes alkyles voisins que le groupe carbonyle. II n'existe pas de relation directe avec la transition π^
