Sulfurimidoyl difluorides (RNSOF2) are excellent multidimensional SuFEx hubs, however their preparation from the scarcely available thionyl tetrafluoride (SOF4) gas limits this chemistry. Here, we propose silver pentafluorooxosulfate (AgOSF5) as a viable alternative to SOF4. Prepared by the AgF2-mediated oxidation of SOCl2, we found that the adduct produces sulfurimidoyl fluorides in high yields from
磺
酰亚胺酰二
氟化物 (RNSOF 2 ) 是优秀的多维 SuFEx 中心,但它们由稀缺的四
氟化亚
硫酰 (SOF 4 ) 气体制备而成,限制了这种

氟氧
硫酸银(AgOSF 5 )作为 SOF 4的可行替代品。通过AgF 2介导的SOCl 2氧化制备,我们发现该加合物从

硫酰氟,也可扩展到AgOSF 4 CF 3 。
