hypervalent iodine(III) reagents incorporating transferable sulfoximidoyl groups were obtained through ligand exchange reactions of methoxy(tosyloxy)iodobenzene (MTIB) with NH sulfoximines in good to excellent yields. The solid‐state structure of a representative product was characterized by X‐ray crystallography. Utilizing these reagents in synthesis provides a new, transition‐metal‐free approach towards
通过甲氧基(甲苯磺酰氧基)碘代苯(MTIB)与NH亚砜亚胺的配体交换反应,可以很好地获得具有可转移的亚磺酰亚胺基的明确定义的高价碘试剂。代表性产品的固态结构通过X射线晶体学表征。在合成中使用这些试剂为N-炔基化亚砜亚胺提供了一种新的无过渡金属的方法。
