General description

Sulfur monochloride is a yellowish-red liquid widely used as a reagent and intermediate in organic synthesis. It is also employed in manufacturing pesticides, pharmaceuticals, and dyes.

Application

Sulfur monochloride can be used:
  • To synthesize functionalized aryl and heteroaryl disulfides from functionalized zinc organometallics.
  • As a reagent to prepare heterocycles with various numbers of sulfur atoms.
  • As a cross-linking agent to prepare rubber aerogels with enhanced thermal stability.
  • Toprepare macroporous cryogels of polyisobutylene and silica nanoparticles.
