ketones in the reaction of organolithiums with lithiumcarboxylates. The CeIII suppresses the enolization of the lithiumcarboxylate, previously unrecognized as a competing reaction except in special cases, and the formation of tertiary alcohols. One of the reasons for the latter effect is a surprising increase in the rate of addition of the organometallic to the lithiumcarboxylate in the presence
