A Novel Electrophilic Diamination Reaction of Alkenes

A three‐component electrophilic reaction transforms olefins into imidazoline and diamine derivatives (see scheme). Rhodium(II) heptafluorobutyrate dimer (2 mol %) was utilized as the catalyst and N,N‐dichloro‐p‐toluenesulfonamide (TsNCl2) and acetonitrile as the nitrogen sources. Modest to good yiel...

Zusammenfassung:	A three‐component electrophilic reaction transforms olefins into imidazoline and diamine derivatives (see scheme). Rhodium(II) heptafluorobutyrate dimer (2 mol %) was utilized as the catalyst and N,N‐dichloro‐p‐toluenesulfonamide (TsNCl2) and acetonitrile as the nitrogen sources. Modest to good yields (45–82 %) and high regio‐ and stereoselectivity were achieved.
