Organometallic reagents cerium

A diastereoselective synthesis of vicinal diamines has been described79. The aldehydes 56 derived from chiral amino acids 55 were converted into the A-benzylimines 57 and the latter were treated with organometallic reagents R2M in the presence of cerium(III)... [Pg.547]

Organolithiums can be converted to other types of organometallic reagents by transmetallation— simply treating with the salt of a less electropositive metal. The more electropositive lithium goes into solution as an ionic salt, while the less electropositive metal (magnesium and cerium in these examples) takes over the alkyl group. [Pg.217]

Reviews of carbanionic reactions in synthesis have addressed the use of organo-cerium compounds and ketone formation by reactions of acyl chlorides with organometallic reagents. ... [Pg.391]
