应用

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.
