Abstract

An inexpensive and experimentally simple, iron‐catalyzed N‐arylation reaction of NH‐sulfoximines with aryl iodides is reported. This complementary method to the known palladium‐ and copper‐catalyzed ones features the use of a combination of environmentally friendly FeCl~3~ and N,N′‐dimethylethylenediamine (DMEDA) as catalytic system and allows the efficient preparation of various N‐arylsulfoximines in high yields.
