Sulfoximines bearing pyrazolylmethyl and arylsubstituents, which are relevant to the crop protection industry, and their corresponding sulfilimine intermediates, have been prepared from sulfide precursors by either iron-catalyzed nitrogen transfer reactions or metal-free imination procedures. Whereas the former approach leads to N-nosyl-substituted products, the latter affords N-cyano derivatives
