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.
Direct arylation of alkenes with aryl iodides/bromides through an organocatalytic radical process
A radical addition: A KOtBu-complex-promoted radical arylation of polysubstituted alkenes with aryl iodides/bromides proceeds in high efficiency (see scheme). Benzofuran derivatives are also produced starting from readily available allyl 2-iodophenyl ethers. Copyright
