- Thiocyanohydrins, a new class of compounds, precursors of unstabilized thiocarbonyl derivatives
-
Mono- and dialkylated thiocyanohydrins are prepared by alkylation of the parent compound 2 (NCCH2SH) under mild conditions. Some examples of the reactivity of this new class of compounds are also given.

-
Thiocarbonyl derivatives R1R2C=S with R1, R2 = H, CH3, C6H5 can be generated thermally in the gas phase from a variety of precursors.Especially advantageous are the cleavage of propene from allyl sulfides or, for their preparation in pure form, the pyrolysis of dithietane or trithiolane derivatives.Photoelectron spectroscopy proves to be well-suited for gas analysis in the flow tube used, for the optimization of the decomposition conditions, and via assignment of the observed ionization patterns for the characterization of the thioaldehydes and thioketones prepared.

- Etude des spectres de masse des thiocetones cyclaniques et α-cyclaniques; mecanismes des fragmentations
-
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.
