Methyl disulfide

The methyl disulfide was obtained from the Crown Zeller-bach Corporation, Chemical Products Division, Camas, Washington, and redistilled. The 108-109° boiling fraction was used. [Pg.63]

Examples of photochemical methods of addition to acetylene derivatives are the addition of methyl disulfide to hexafluoro-2-butyne [7] (equation 8), of trifluaramethanethial to methyl propiolate [S] (equation 9), of methanethiol to trifluoromethylacetylene and hexafluoro-2-butyne [9] (equation 8), and of tri-methylsilane to tetrafluoropropyne [10. ...

Owing to a very dissymmetric tt-charges distribution on the S—S bridge in aryl methyl disulfides, 4-RC6H4SSMe, the cation radicals of these compounds behave like those of alkyl aryl selenides, undergoing a potential-determined cleavage of the S—S bond or a deprotonation of the methyl group [124,125].

The synthesis of isomeric l,2,3,4-tetrakis(methyl-thio)hexafluoro-n-butane was finally achieved by photoassisted sonication, after the numerous attempts through the various methods had failed. A successful method described here consists of reacting trans-1,4-bis(methylth1o)hexafluoro-2-bu-tene in an excess of methyl disulfide with an added appropriate gas (hexafluoropropane) to increase and control the pressure in the reaction vessel. The heterogeneous mixture was then subjected to the combined photolysis and sonication at 50°C. The iaFNMR and mass spectral data of the product and the by-product l,2,4-tris(methylth1o)-3-H-hexafluo-ro-n-butane were presented. [Pg.287]
