Interconversion of organonitrogen oxides: Nitrosyl, nitrosoalkane, and hydroxylamido(1−) ligands are interconverted on an organoruthenium platform (see structure and scheme). These stepwise and sequential reactions provide insights into the mechanism of the biological nitrite–ammonia interconversion, a major process in the inorganic nitrogen cycle in which nitric oxide, nitroxyl, and hydroxylamine have been invoked as intermediates.
