Application
Iron(II) chloride tetrahydrate can be used as a catalyst in the:
- Solvent-free Ritter reaction of nitriles with various halohydrocarbons to synthesize N-substituted amides.
- Synthesis of ketones via indirect hydration of alkynes.
- Stereoselective reduction of α, β-unsaturated carbonyl compounds to the corresponding saturated alcohols in the presence of lithium and DTBB.
