Iron(MCP) Complexes Catalyze Aziridination with Olefins As Limiting Reagents.

Herein described are the first efficient nitrogen-atom transfer reactions mediated by iron N, N'-dimethyl- N, N'-bis(2-pyridinylmethyl)cyclohexane-1,2-diamine- (MCP-) and 2-({1-[(pyridin-2-ylmethyl)pyrrolidin-2-yl]pyrrolidin-1-yl}methyl)pyridine-type (PDP-type) complexes. These catalysts affect styrene aziridination under mild conditions based on a limiting quantity of olefin substrate.
