A mixture of LiAlHi and CeCls is a powerful reducing agent, reducing unsaturated carbonyl compounds to allylie alcohols (in this case, anhydrous cerium chloride is a necessity). It will reduce phosphine oxides to phosphines, oximes to primary amines, and o ,jS-unsaturated carbonyl compounds to allylie alcohols. In particular, it reduces both aryl and alkyl halides to hydrocarbons.

The reaction with CeOj was incorrectly reported as yielding CeCl [360]. Cerium(IV) oxide reacts with phosgene to initially form cerium(lll) oxide chloride, which can then react with further phosgene (see Section 9.3.1). Thus, the stoicheiometry of the two possible overall reactions is [307,1088,2042] ... 

Cerium(in) chloride mediates nucleophilic attack of MesSiCHzMgCl to esters to form aUylsilanes. The reaction allows the syntheses of aUylsilanes having a functionalized alkyl chain at the fi position. As a representative, the reactions of chiral /3-hydroxy- and /3-amino ester with Me3SiCH2MgCl in the presence of CeCls provide chiral aUylsilanes, which are applicable to the synthesis of natural products (eq 16). ...
