Metal-Free Approach for the Synthesis of N-Aryl Sulfoximines via Aryne Intermediate
摘要:
A metal-free and operationally simple N-arylation of NH-sulfoximines with precursors is reported. Transition metal-free reaction conditions and Shorter reaction times are the highlights of the present method. The mild optimized condition was :also found to be suitable with enantiopure substrates.

An inexpensive and experimentally simple, iron-catalyzed N-arylation reaction of NH-sulfoximines with aryliodides is reported. This complementary method to the known palladium- and copper-catalyzed ones features the use of a combination of environmentally friendly FeCl3 and N,N′-dimethylethylenediamine (DMEDA) as catalytic system and allows the efficient preparation of various N-arylsulfoximines in
