We herein report an unprecedented xanthate-based protocol for the preparation of aryl-alkyl thioethers. Heating xanthates with aryl halides and namely cesium carbonate in methanol provides the target thioethers in generally good yields within short reaction times. This method allows one to avoid contact with odorous thiols and also to introduce substituents of which the corresponding thiols are virtually unavailable or inconvenient in use.
Preparation method of xanthate compound
-
Paragraph 0037; 0038, (2020/11/05)
The invention discloses a preparation method of an xanthate compound. The method is characterized in that an xanthate and a chloride react at 0-60 DEG C in the presence of a phase transfer catalyst toprepare the xanthate compound with high purity and high yield. Compared with the existing method, the process for preparing xanthate compounds by phase transfer catalysis without solvent (self-solvent) is simple, the product purity is good, the yield is high, and the method is economic and environment-friendly and is suitable for industrial production.

Paragraph 0020; 0021, (2017/03/17)
The invention discloses a alkyl xanthic sour alkene propyl ester compound of preparation method. A alkyl xanthic sour alkene propyl ester compound of preparation method, used for preparing alkyl xanthogen ally propyl ester dressing agent. Characterized in that a safe, non-corrosive to the allylic alcohol compound alternative flammable, extremely volatile allyl chlorine apperception compound as raw material, with the alkyl xanthic acid salt reaction for preparing alkyl xanthogen ally propyl ester compounds, through the liquid, washing, and drying to obtain alkyl xanthic sour alkene terephthalate, thus make the production process more environmental protection, security.

Facile Syntheses of 1,3-Dithiol-2-ones and 1,3-Dithiole-2-thiones
Haley, Neil F.,Fichtner, Michael W.
, p. 2959 - 2962 (2007/10/02)
A facile ring closure of allyl xanthates or trithiocarbonates with iodine is discussed.The products of the reaction undergo basic dehydroiodination and acidic isomerization to give 1,3-dithiol-2-ones and -2-thiones in high yield.

Pesticidal composition comprising: a pesticidal, phosphoric ester the molecule of which has at least one alkyl group of 1 to 3 carbon atoms, 0.05 to 10% of an agent stabilizing the said ester against decomposition by protonisation, together with adjuvants characterized in that the stabilizing agent comprises at least one sulphur compound containing per molecule at least one divalent sulphur atom of which one valence is bonded to an atom chosen from sulphur, carbon, nitrogen, hydrogen, and metals capable of giving a salt, the other valence being bonded to an atom chosen from hydrogen, the carbon atom already noted, a second carbon atom, the nitrogen atom already noted, a second nitrogen atom, the metal atom already noted in the case of a metal of valence greater than one, a second atom of metal and oxygen when the first valence is not attached to an atom of hydrogen, the proportion of sulphur calculated with reference to the weight of the sulphur compound being between 5 and 99%. Process for stabilizing a phosphoric ester of which the molecule possesses at least one alkyl group containing 1 to 3 carbon atoms characterized in that there is added to the phosphoric ester or to a mixture which contains it, 0.05 to 10% calculated on the weight of the phosphoric acid ester of an agent capable of stabilizing the said phosphoric ester against protonisation and comprising at least one sulphur compound such as that defined thereupon.
