DESCRIPTION
General description
Zinc chloride is a strongly hygroscopic deliquescentsolid widely used as a Lewis acid catalyst in a variety of organictransformations.
Application
Zinc chloride is used as a catalyst:
- in Knoevenagel condensation of carbonyl substrates with acidic methylene reagents[1]
- in solvent-free synthesis of dihydropyrimidinones.[2]
It may be used as chemical activating agents, zinc chloride in particular is the most widely used chemical in the preparation of activated carbon.[3] |
