Description:
Lanthanum chloride (LaCl3) is a chemical compound. It is used as a mild Lewis acid to perform chemical reactions that usually require acidic conditions, such as converting aldehydes to acetals, under nearly neutral conditions.
The lanthanide ions are 9 coordinate in the trichloride.
The compound has been identified as a catalyst for the high pressure oxidative chlorination of methane to chloromethane with hydrochloric acid and oxygen. Although lanthanides are known for both +3 and +4 oxidation states , this does not apply to lanthanum itself. The neutral atom only carries three electrons in its outer shell. Therefore the oxidation state of lanthanum remains unchanged in this highly oxidative environment.
