Thermal degradation of four polysulphides, poly(methylenesulphide), poly(methylenedisulphide), poly(methylenetetrasulphide), and poly(styrenesulphide)-co-poly(methylenesulphide) have been investigated by pyrolysis gas chromatography/mass spectrometry technique (Py-GC/MS). The pyrolysis products detected by Py-GC/MS indicate that the thermal decomposition of these polymers yields cyclic sulphides by an intramolecular exchange process. The linear products with thiol end groups also form along with the cyclic products through a β-CH hydrogen transfer reaction.
HIGH-TEMPERATURE ORGANIC SYNTHESIS. XXVI. REACTIONS OF ALKANETHIOLS AND DIALKYL SULFIDES AND DISULFIDES WITH VINYL CHLORIDE

An abnormal directions was established in the thermal reactions of alkanethiols and dialkyl sulfides and disulfides with vinyl chloride, leading to the formation of the corresponding 1,1-bis(alkylthio)ethanes.
The Lithium Diisopropylamide-induced Fragmentation of 1,3-Dithiolane Derivatives of Several Ketones Having α-Hydrogen

The reaction of 1,3-dithiolane derivatives of ketones having a-hydrogen with lithium diisopropylamide results in fragmentation to the corresponding thioketone followed by further conversion in a few steps to the other intermediate species which, on trapping with alkyl halide, leads to a vinylic sulfide and/or a sulfide bearing a secondary alkyl group.
