The synthesis of C12H8I2N2O, an unexpected product, obtained while converting N,N-dibutyl-4-iodoaniline into its N-oxide, was presented. A mixture of N,N-dibutyl-4-iodoaniline, chloroform, methanol, and hydrogen peroxide was heated to reflux. Until the starting material was fully consumed, the addition of hydrogen peroxide was continued. The product was then isolated, and allowed to get crystallized into colourless crystals. The product was found to crystrallize as a layer structure.
