Descripción

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.
