Electrochemical Synthesis of Organic Polysulfides from Disulfides by Sulfur Insertion from S8 and an Unexpected Solvent Effect on the Product Distribution

An electrochemical synthesis of organic polysulfides through sulfur insertion from elemental sulfur to disulfides or thiols is introduced. The highly economic, low-sensitive and low-priced reaction gives a mixture of polysulfides, whose distribution can be influenced by the addition of different amounts of carbon disulfide as co-solvent. To describe the variable distribution function of the polysulfides, a novel parameter, the “absorbance average sulfur amount in polysulfides” (SAP) was introduced and defined on the basis of the “number average molar mass” used in polymer chemistry. Various organic polysulfides were synthesized with variable volume fractions of carbon disulfide, and the yield of each polysulfide was determined by quantitative 13C NMR. Moreover, by using two symmetrical disulfides or a disulfide and a thiol as starting materials, a mixture of symmetrical and asymmetrical polysulfides could be obtained.

Rhodium-catalyzed sulfur atom exchange reaction between organic polysulfides and sulfur

RhH(PPh3)4 and cis-1,2-bis(diphenylphosphino)ethylene (dppv) catalyze the exchange of sulfur atoms between sulfur and organic polysulfides. The exchange of dialkyl trisulfides with sulfur proceeds at a high efficiency within 5 min at room temperature yielding a mixture of organic polysulfides.

Highly Efficient Solvents and Reagents for Elemental Sulfur

Elemental sulfur is easily activated in the hydrazine hydrate-alkali system with formation of polysulfide anions. The procedure is developed for yielding highly concentrated solutions of alkali metal polysulfides. The latter compounds are readily alkylated with alkyl halides to form dialkyl polysulfides. The alkylation using higher alkyl halides (C7-C9) yields dialkyl sulfides that are difficult to prepare by other methods.

Use of a sacriflcial-sulfur electrode in electroorganic chemistry. V. Formation of the sequence CSSSC from S and thiols or thiolates

At a working potential of about +2.0 V (vs SCE) the carbon-sulfur electrode is a source of the electrogenerated cation S2+. In organic media, this electrophile reacts with thiols (or thiolates) to give a mixture of polysulfides of which the trisulfide is the main product. The reaction between electrogenerated Sy2- and alkyl halides is less selective. Elsevier,.
