A comparative evaluation was made on the syntheses of vicinal halohydrins, halo methyl ethers, and halo acetates from olefins using 2:1 Br-/BrO3- and I-/IO3- reagents. In many cases both reagents afforded products selectively in high yields. The highest halogen atom efficiencies attained were 97% and 93% for Br-/BrO3- and I-/IO3-, respectively. Of the two reagents, I-/IO3- was established to be the preferred reagent for vicinal functionalization of linear alkenes and also for halo acetate preparation. However, only Br-/BrO3- was effective for vicinal functionalization of trans-stilbene and chalcones.

N-Bromo and N-iodosaccharin react with electron-deficient alkenes such as α,β-unsaturated ketones, acids, esters and nitriles in aqueous organic solvents, yielding the corresponding halohydrins in good yields. The reactions take place at room temperature,

Two new convenient systems for electrophilic iodochlorination of olefins are proposed: KIO3 + I2 + HCl (in aqueous solutions) and KICl4 + I2 (in organic solvents).
Versatile iodination of olefins by potassium dichloroiodate(I)

, p. 1359 - 1361 (2007/10/02)
The versatile electrophilic iodination of double bonds with potassium dichloroiodate(I) is described. In most examples various β-substituted iodides, particularly vic-iodochlorides were synthesised in excellent yields.
