Manufacturing method of sulphides

A method of manufacturing a sulfide comprises the steps of (a) dissolving a thiol in a solvent to form a solution; (b) oxidizing the thiol to a disulfide in the presence of a first oxidizing agent in the solution; (c) reacting the disulfide with a coupler in the presence of a base and a second oxidi...

Zusammenfassung:A method of manufacturing a sulfide comprises the steps of (a) dissolving a thiol in a solvent to form a solution; (b) oxidizing the thiol to a disulfide in the presence of a first oxidizing agent in the solution; (c) reacting the disulfide with a coupler in the presence of a base and a second oxidizing agent, without isolation of said disulfide from the solution, to form a reaction mixture in which the sulfide is produced; and (d) obtaining said sulfide.
