The reaction of lithium dialkylcuprates with acid chlorides gives ketones in excellent yield. Because ketones are much less reactive than acid chlorides toward lithium dialkylcuprates, they do not react further. The reaction of acid chlorides with lithium dialkylcuprates is one of several excellent meth-
