A scalable rhodium-catalyzed intermolecular aziridination reaction.

The amine has landed! By employing the rhodium catalyst [Rh2 (esp)2 ] in the presence of a readily available amine source (DPH), unactivated and styrene-type olefins can now be stereospecifally transformed, in high yields at room temperature, into valuable NH aziridine products. esp=α,α,α',α'-tetramethyl-1,3-benzenedipropionic acid.
