说明

應用

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.
