Uses

Used in Analytical Chemistry:
DI-SEC-BUTYL SULFIDE is used as a chemical reference material for the determination of dialkyl sulfides. It plays a crucial role in the development and validation of novel micropacked columns prepared from the slurry of bis[1,2-bis(4-n-undecyloxyphenyl)ethane-1,2-dithiolene]nickel(II) coated on chromosorb W. This application is particularly relevant in micropacked gas chromatography, where the compound aids in the accurate identification and quantification of dialkyl sulfides in various samples.

Direct synthesis of disulfides from alkyl halides using thiourea and CCl4 in glycerol

Abstract Dialkyl disulfides were obtained on the basis of the reaction of alkyl halides and thiourea in the presence of CCl4 and Et3N. This procedure enables the odorless and one-pot synthesis of disulfides by employing cheap, easy-to-handle and readily available reagents and substrates in wet glycerol.

Highly efficient and functional-group-tolerant catalysts for the palladium-catalyzed coupling of aryl chlorides with thiols

The cross-coupling reaction of aryl chlorides with aliphatic and aromatic thiols catalyzed by palladium complexes of the strongly binding bisphosphine CyPF-tBu ligand (1) is reported. Most of the reactions catalyzed by complexes of ligand 1 occur with turnover numbers that exceed those of previous catalysts by two orders of magnitude. The reactions occur with excellent yields, broad scope and high tolerance of functional groups. Coupling of aryl halides with thiols in the presence of low loadings of catalysts derived from other Josiphos type ligands, as well as ligands of other structural types, are also described.

Deoxygenation and Desulphuration Reactions of Lithium: Part V - Reaction of Sulphoxides with Lithium

Dialkyl and aralkyl sulphoxides are reduced to the corresponding sulphides in good yields by lithium in dimethoxyethane; however, the reaction of benzyl sulphoxides with lithium is more complex.

Nucleophilic Substitution of Alkyl Halides by Zinc Salts: Part 4-Synthesis of Thioethers and Thiolesters

A variety of alkyl halides including tertiary alkyl halides react smoothly with the zinc salts of thiols and thiolcarboxylic acids yielding thioethers and thiolesters.

Chemical Conversions using Sheet Silicates: Novel Intermolecular Eliminations of Hydrogen Sulphide from Thiols

Aliphatic primary and secondary thiols react in the interlamellar layers of ion-exchanged montmorillonite catalysts to produce dialkyl sulphides via intermolecular elimination of hydrogen sulphide; similar processes result in the production of diphenyl sulphide from benzenethiol and poly(phenylenemethylene) from α-toluenethiol.

ACTION OF ELEMENTARY SULFUR ONTO CARBANIONS: A NEW ROUTE TO DIALKYLPOLYSULFIDES

The reaction of sec-Butyllithium with elemental sulfur leads to the formation of dialkylpolysulfides.
