Abstract

Sulfoximines bearing pyrazolylmethyl and aryl substituents, 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.
