General description

Cobalt(II) chloride is an anhydrous cobalt salt. Cobalt(II) chloride participates in the synthesis of various esters in the presence of acetonitrile.

Application

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.
Cobalt(II) chloride may be employed as a catalyst in the following studies:
  • Acylation of various alcohols (primary and secondary).
  • Acylation of various hydroxyl compounds (high selectivity).
  • Regioselective ring-opening reaction of oxiranes.
  • Coupling reactions of anhydrides or acid chlorides with thiols.
  • Protection of aldehydes, via chemoselective dithioacetalization reaction.
  • Solvent-free synthesis of β-enaminones and β-enamino esters.
