Ruthenium porphyrin catalysed direct intermolecular amino-oxyarylation of alkenes including styrenes and 1,3-dienes to give primaryamines with O-(2,4-dinitrophenyl)hydroxylamine as the amine source was achieved in moderate to good yields under mild reaction conditions. Spectroscopic analyses revealed that a ruthenium nitrido complex was the key reaction intermediate for the amino-oxyarylation reaction

A method for the direct stereospecific conversion of structurally diverse mono-, di-, tri- and tetra-substituted olefins to N—H, N-alkyl, N-cycloalkyl, or N-aralkyl aziridines using a hydroxylamine amination agent with transition metal catalyst. The method is operationally simple (i.e., one-pot), scalable and fast at ambient temperature.
