We proposed a new simple method for preparation of new dibenziodonoium salts via oxidation of 2-iodobiphenyl in the presence of appropriate acids followed by ligand exchange on the next step. [O]=mCPBA, Oxone; H+A-= H2SO4, HOTf, HNTf2; X = -SCN, -N3, -CN, -OH, -Cl, -Br, -OSOPh The structure of obtained compounds was investigated by X-Ray study. Obtained dibenziodonium salts derivatives could be applied as new reagents for transfer of nucleophilic functional groups in organic synthesis. References  Zhu D., Liu Q., Luo D. et al. Adv. Synth.
