The direct α-iodination of various ketones using iodine-ammonium cerium(IV) nitrate in acetic acid or alcohol gave the corresponding α-iodo ketones in high yields. The effect of cerium salt on the iodination of ketones, and the iodination of 5α-cholestan-3-one using several methods are also discussed. In the reaction of 3,3,5-trimethylcyclohexanone and unsymmetrical ketones, such as 2-hexanone and

Abstract Iodination of enolacetates and 1,3-diones with N-iodosaccharin yielding the corresponding α-iodoketones and 2-iodo-1,3-diones is presented. Reactions are carried out at room temperature under neutral conditions and in short reaction times.

The reaction of triiodoisocyanuric acid (prepared from I2 and trichloroisocyanuric acid in 90% yield) with alkenes in the presence of oxygenated nucleophilic solvents (alcohols, AcOH and H2O) led to the corresponding β-iodoethers, β-iodoacetates and iodohydrins, in 66–98% isolated yield. Enolethers reacted with triiodoisocyanuric acid in MeOH to produce dialkylacetals (70–83%).
