Tu, Yongqiang published the artcileSynthesis of 9-iminedibenzocycloiodonium salts, HPLC of Formula: 1821-27-8, the publication is Lanzhou Daxue Xuebao, Ziran Kexueban (1990), 26(1), 30-4, database is CAplus.

Cyclic iodonium compounds I (R, R1 = NO2, NHAc, Br, Cl, iodo; X = Cl, iodo) were prepared starting from 4,4′-dinitrodiphenylamine (II). E.g., iodination of II with I2/SbCl5 gave 75% 2,2′-diiodo-4,4′-dinitrodiphenylamine, cyclization of which with K2S2O8/H2SO4 gave, after treatment with NaCl/HCO2H, 45% I (R = R1 = NO2, X = Cl).
