The development of the Cope-typehydroamination as a method for the metal- and acid-free intermolecularhydroamination of hydroxylamines with alkenes and alkynes is described. Aqueous hydroxylamine reacts efficiently with alkynes in a Markovnikov fashion to give oximes and with strained alkenes to give N-alkylhydroxylamines, while unstrained alkenes are more challenging. N-Alkylhydroxylamines also

An exclusively chelating ligand bridged high-valent [MnIV3] complex has been synthesized, in which all Mn(IV) ions are ferromagnetically-coupled to exhibit an S(T) = 9/2 spingroundstate.
