Application
Copper(II) chloride dihydrate may be used in the following processes:
- As a recoverable promoter for the conversion of oximes to carbonyl compounds under mild reaction conditions.
- To catalyze Biginelli condensation of aldehyde, β-ketoester and urea or thiourea to form dihydropyrimidinones under solvent-free and microwave irradiations.
- Along with stannous chloride for the allylation of aldehydes.
