Beschreibung

Anwendung

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.

It can also be used as:

• A precursor to prepare hafnium oxide nanoparticles via sol-gel method.
• A starting material to synthesize bulky guanidinato hafnium(iv) chloridecomplexes.
