Applicazioni

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.
It can also be used as a precursor to prepare iron-bisphosphine complex, which can be used to catalyze Kumada­-Tamao-­Corriu coupling.
