DESCRIPTION
General description
Lanthanum(III) nitrate hexahydrate is a transition metal catalyst widely used in many organic transformations such as chemoselective deprotection of acetonides, acetylation of alcohols, phenols, and amines with acetic anhydride, and synthesis of α-amino nitriles. It can also be used as a precursor in the preparation of lanthanum-based nanoparticles. Application
Lanthanum(III) nitrate hexahydrate can be used as a catalyst in the synthesis of:
α-aminonitriles by a one-pot three-component coupling of the carbonyl compound, amine, and TMSCN.
Acetals and geminal diacetates (acylals)from aldehydes. Bis(indolyl) methanes under solvent‐free conditions.
It can also be used as a starting material for the electrochemical synthesis of LaMnO3 thin films and solvothermal synthesis of doped lanthanide oxysulfide (La2O2S).
