Abstract

Ketones are prepared by admixing at least one gem-dichloro compound with at least one acid such that the ketone wherein the keto-oxygen replaces the gem-dichloro group is formed. The reaction is exemplified by the reaction of 9,9-dichlorofluorene with an acid such that fluorenone is formed. This process has the advantage that no oxidizing agent is used.
