Application
Hafnium(IV) chloride can be used as a catalyst:
- To synthesize α-aminophosphonates via the one-pot three-component reaction of aldehyde, amine, and phosphite.
- For the conversion of carbohydrates into 5-hydroxymethylfurfural in ionic liquids.
- For parallel synthesis of 1,2-disubstituted benzimidazoles from N-substituted phenylenediamines and aldehydes.
- A precursor to prepare hafnium oxide nanoparticles via sol-gel method.
- A starting material to synthesize bulky guanidinato hafnium(iv) chloridecomplexes.
