General description
Cobalt(II) chloride hexahydrate, also known as cobaltous chloride hexahydrate, is a hydrated form of cobalt and chloride. It is a crystalline solid consisting of octahedral complexes, with the coordination polyhedron of the Co2+ ion including four H2O molecules and two Cl− ions. It is highly soluble in water and is commonly used as a catalyst in various organic synthesis, such as during the synthesis of benzimidazole and biscoumarin derivatives.
Application
Cobalt(II) chloride hexahydrate can be used as a catalyst for the:
- Dioxygenation of styrenes with N-hydroxyphthalimide to synthesize corresponding alcohols and ketones.
- Oxidative coupling of primary amines to imines.
- Friedel-Crafts reaction between indoles and activated olefins to synthesize β-indolylketones.
- Synthesis of β-enaminones and β-enamino esters.
- Reaction of acyl chlorides with diselenides or disulfides to synthesize selenol and thiol esters.
