Thermal degradation processes in polysulphide polymers investigated by flash pyrolysis gas chromatography/mass spectrometry

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.

DIVINYL SULFIDE. XIV. DIVINYL SULFIDE AND SULFUR-CONTAINING HETEROCYCLES FROM VINYL HALIDES AND SODIUM SULFIDE

The reaction of vinyl halides with hydrated sodium sulfide in the potassium hydroxide-DMSO (HMDTA) superbasic system leads to the formation of divinyl sulfide, 2,5-dimethyl-4-methylene-1,3-oxathiolane, 2,4,5-trimethyl-1,3-oxathiole, and 2-thiabicyclohept-3-ene and also dimethyl sulfide, vinyl methyl sulfide, and vinyl ethyl sulfide.The effect of the reaction conditions (temperature, solvent, time, and ratio of reagents) on the yield of the products and the selectivity of the process was studied.

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.
