CeCl3(thf) reacts at low temperatures with MeLi, t-BuLi, and n-BuLi to isolable organocerium complexes. Solvent-dependent extensive n-BuLi dissociation is revealed by 7Li NMR spectroscopy, suggesting “Ce(n-Bu)3(thf)x

The addition of Grignard reagents to ketones is significantly enhanced by cerium chloride with remarkable supression of side reactions, particularly enolization.Some esters, which are prone to side reactions, also react readily with Grignard reagents in the presence of cerium chloride to give normal reaction products in reasonable to high yields.
ORGANOCERIUM REAGENTS. NUCLEOPHILIC ADDITION TO EASILY ENOLIZABLE KETONES
Imamato, Tsuneo,Sugiura, Yasushi,Takiyama, Nobuyuki
, p. 4233 - 4236 (2007/10/02)
Organocerium reagens, prepared from organolithiums and anhydrous cerium (III) chloride, react cleanly with easily enolizable ketones to afford the addition products in good to excellent yields.
