Application
CoCl2 can be used as a catalyst:
- For the dealkylation of tertiary amines.
- In the synthesis of thioketones and thioaldehydes via thionation of carbonyl compounds in the presence of bis(trimethylsilyl) sulfide.
- In the oxidation of aromatic and aliphatic aldehydes to carboxylic acids in the presence of molecular oxygen and acetic anhydride.
- In the stereoselective opening of epoxides with N-substituted anilines.
CoCl2 can also be used as:
- A precursor to synthesize magnetic cobalt nanorods via decomposition of the cobalt coordination complex.
- A catalyst to prepare acid anhydrides by the reaction of acid chlorides with carboxylic acids.
- A reagent in the carbon-carbon bond-forming reactions involving active methylene compounds.
