Application
Dimethyl disulfide can be used:
- For the sulfidation of WS2 nanoparticles during the preparation of WS2/SBA15 mesoporous silica composite.
- In the copper-catalyzed sulfenylation of 2,3-allenoic acids to afford 4-sulfenylated butenolides.
- To synthesize various aryl sulfides by nickel-catalyzed thiolation of aryl iodides.
- Along with triflic anhydride, as a promoter for glycosylation reaction.
- In the copper-catalyzed 1,2-hydroxysulfenylation of alkenes to synthesize 1,2-acetoxysulfides.
- In the synthesis of sulfur containing polycyclic aromatic hydrocarbons such as dibenzoannelated tetrathienoacene.
