Vinylsulfides are often obtained via the reaction of substituted acetylenes with sulfur-containing reagents. The presence of other functional groups such as the halide or the hydroxyl moieties enhances the usefulness of the vinylsulfide intermediates. To this end, propargyl alcohol and halides have found wide application. With a view to enhance the biological properties of the end products synthesized from the vinylsulfide intermediates, the trifluoromethylthio function has now been incorporated as a part of the vinylic system. This communication presents the free-radical addition of trifluoromethyl-sulfenyl chloride to 3-chloro- and 3-hydroxypropynes, and the mechanism of the formation of the various products and their spectral characterization.

Paragraph 0067; 0071-0073; 0079-0083; 0087-0091; 0095-0099, (2020/11/10)
The invention provides a method for treating byproducts in a process for preparing chloropropene by propylene chlorination. The method comprises the following steps: separating byproducts in a processof preparing chloropropene by propylene chlorination to obtain cis-1, 3, 5-triazolo[1, 2-a]pyridin-2-carboxylic acid. According to the method, trans-1, 3-dichloropropene reacts and is converted intotrans-1, 3-dichloropropene with higher additional value under the illumination condition and the catalytic action of the catalyst, so that the economic value of byproducts in the process of preparingchloropropene by propylene chlorination is improved, the cost of the whole process is greatly reduced, and the method has a good industrial application prospect.
