The transfer of a single electron leads to intermediate radical ions, whose strongly modulated reactivities can be exploited for asymmetric catalysis in a novel fashion. All processes discussed here are redox neutral so that the electron serves as a real catalyst which cooperates with an asymmetric catalyst for the overall asymmetric transformation. ER -
