Abstract

UV photolysis of the nitridoosmate(VIII) anion, OsO3N, in low-temperature frozen matrices results in nitrogen–oxygen bond formation to give the OsII nitrosyl complex OsO2(NO). Photolysis of the OsII nitrosyl product with visible wavelengths results in reversion to the parent OsVIII complex. Formally a six-electron reductive elimination and oxidative addition, respectively, this represents the first reported example of such an intramolecular transformation. DFT modelling of this reaction proceeds through a step-wise mechanism taking place through a side-on nitroxyl OsVI intermediate, OsO22-NO).
