Iron-catalysed stereoselective NH transfer enables dynamic kinetic resolution of sulfoxides by Fang-Xu Fan, Hui Xu, Shi-Xiong Tang, Yanfeng Dang, Fei Wang

“…Computational studies on the NH imidation reaction suggest the involvement of an iron-aminyl radical intermediate, and its reaction with sulfoxide proceeds through a synchronous nucleophilic addition of sulfoxide to nitrogen center and ligand-to-metal single electron transfer process to form the N–S bond. In addition, the stereoselectivity is primarily dictated by the difference in dispersion interactions of the transition states.…”
