Cu(II)-mediated direct NH2 and NH alkyl aryl aminations and olefin aziridinations are described. These room-temperature, one-pot, environmentally friendly procedures replace costly Rh2 catalysts and, in some instances, display important differences with comparable Rh2- and Fe-supported reactions.

methods are devoted to their activated counterparts. Herein, we have developed a highly efficient Rh(II)-catalyzed method for the direct preparation of unactivated aziridines from olefins using O-(sulfonyl)hydroxylamines as the aminating agent. The reactions proceed with a high stereospecificity.

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.
