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
带有吡唑基甲基和芳基取代基的与农作物保护工业有关的亚磺酰亚胺及其相应的亚硫亚胺中间体,是由硫化物前体通过铁催化的氮转移反应或无金属的亚胺化方法制备的。前一种方法可产生N-烷基取代的产物,而后者可提供N-氰基衍生物。
