Abstract: | A reliable synthesis of unstable and highly reactive BrO2F is reported. This compound can be converted into BrO2+SbF6?, BrO2+AsF6?, and BrO2+AsF6??2 BrO2F. The latter decomposes into mixed‐valent Br3O4?Br2+AsF6? with five‐, three‐, one‐, and zero‐valent bromine. BrO2+ H(SO3CF3)2? is formed with HSO3CF3. Excess BrO2F yields mixed‐valent Br3O6+OSO3CF3? with five‐ and three‐valent bromine. Reactions of BrO2F and MoF5 in SO2ClF or CH2ClF result in Cl2BrO6+Mo3O3F13?. The reaction of BrO2F with (CF3CO)2O and NO2 produces O2Br‐O‐CO‐CF3 and the known NO2+Br(ONO2)2?. All of these compounds are thermodynamically unstable. |
