Cerium chloride Heptahydrate (CeCl3•7H2O)-Crystalline

Characteristic

 

Cerium(III) chloride (CeCl₃), also known as cerous chloride or cerium trichloride, is a compound of cerium and chlorine. It is a white hygroscopic solid; it rapidly absorbs water on exposure to moist air to form a hydrate, which appears to be of variable composition, though the heptahydrate CeCl3·7H2O is known.

Application

Cerium(III) chloride heptahydrate is used in the preparation of allylsilanes from esters. It is used as a reducing agent in organic synthesis in place of sodium borohydride. In Luche reaction, carvone gives selectively allylic alcohol.
