The reaction of CeCl3-MeLi to tertiary amides has been studied. The reagent prepared from cerium(III) chloride and methyllithium at 0°C adds cleanly to morpholine amides to give the corresponding methyl ketones. Even in the presence of a large excess of the reagent, no tertiary alcohol formation is observed, indicating that the tetrahedral intermediates are stable under the reaction conditions employed.
