Application

Vanadium(III) chloride (VCl₃) can be used as a catalyst to synthesize:

• Dihydropyrimidinone derivatives via a three-component Biginelli condensation reaction between aldehyde, β-keto ester, and urea (thiourea).
• Coumarin derivatives via Pechmann condensation reaction of various phenols and β-keto esters.
• β-amino alcohols by deprotection of epoxides with aromatic amines.
• Diol derivatives by chemoselective cleavage of acetonides in methanol.

VCl₃can also be used as a reducing agent to determine nitrates and nitrites in water samples.[5]
