A novel and recoverable fluorous hydrazine-carbothioate organocatalyst was prepared. It could catalyze α-chlorination of alkyl ketones with N-chlorosuccinimide as chlorine source under mild reaction conditions. The reaction afforded the corresponding α-chlorinated carbonyl compounds with excellent yields at rapid reaction speed.
