Electrochemical Aziridination by Alkene Activation Using a Sulfamate as the Nitrogen Source.

The first direct aziridination of triaryl-substituted alkenes was achieved by means of an electrochemical process that could extend to multisubstituted styrenes. Specifically, hexafluoroisopropanol sulfamate was used as a nucleophilic nitrogen source. Mechanistic experiments suggest that this electrochemical process proceeds by stepwise formation of two C-N bonds through reactions between cationic carbon species and the sulfamate.
