A novel protocol for the synthesis of α-iodoketones from alcohols has been developed. Using water as the reaction medium, ammonium iodide and Oxone® was proven to be an efficient reagent system for this reaction and afforded the corresponding α-iodoketones in moderate to good yields. The generality of this reaction was demonstrated with various secondary alcohols such as benzylic alcohols and aliphatic alcohols (acyclic and cyclic).
