Descripción

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).

Features and Benefits

• Thermal stability
• Low toxicity
• Mild reaction condition
• Chemoselectivity
• Low cost
