precursors in reactions with thioethers under the catalysis of a commercially available Ru(II) complex, from which a variety of sulfimides were synthesized efficiently and mildly. If an allyl group is contained in the thioether precursor, the [2,3]-sigmatropic rearrangement of the sulfimide occurs simultaneously and the N-allyl-N-(thio)amides were obtained as the final products. Preliminary mechanistic studies
所述N- acyloxyamides被用作有效N-市售的Ru(II)配合物,从该多种sulfimides被有效地和温和地合成的催化下酰基氮烯的前体在反应与硫醚。如果在硫醚前体中包含烯丙基,则硫酰亚胺的[2,3]-σ重排同时发生,最终获得N-烯丙基-N-(硫代)酰胺。初步的机理研究表明,钌-类胡萝卜素物质应该是转化的关键中间体。
