WebPierce™ Iodination Reagent (1,3,4,6-tetrachloro-3a,6a-diphenyl-glycoluril) is an oxidising agent that efficiently activates iodine for spontaneous incorporation into protein tyrosyl … WebThe corresponding α-iodoketones were obtained in 83–99% yield. For nitro-substituted aryl ketones, the yield decreased significantly to 53% and formation of the dimethyl ketal product occurred. This protocol stands out due to the use of inexpensive reagents and its excellent iodination yields.
