Popis

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.

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