A series of olefins including α,β-unsaturated ketones, cinnamates, cinnamides and styrenes have been aminobrominated with good yields and excellent diastereoselectivities under mechanical milling conditions, using TsNH2 and NBS as the nitrogen and bromine sources, promoted by (diacetoxyiodo)benzene.

An efficient and practical procedure for the aminohalogenation of electron-deficientolefinspromoted by hypervalentiodinecompounds has been demonstrated. The catalytic efficiency of various hypervalentiodinecompounds with different carboxylic and sulfonic ligands has also been investigated and of these (diacetoxyiodo)benzene exhibited the highest activity. A series of substrates, including α,β-unsaturated
