| Application: | 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. |
| 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. |
| 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. |
