Application

Cesium chloride can be used as:
  • A reagent to synthesize macrocyclic tetralactones via ring-closing metathesis reaction of diolefins in the presence of Grubbs catalyst.
  • An additive in the palladium-catalyzed selective carbonylative coupling of less reactive aryl chlorides with primary and secondary aliphatic and aromatic amines to synthesize aromatic amides.
  • An activator for low-valent titanium reagents that can be used in the reductive coupling of acetophenone.
