Sulfur(VI) fluoride exchange (SuFEx) is a new family of click chemistry based transformations that enable the synthesis of covalently linked modules via SVI hubs. Here we report thionyl tetrafluoride (SOF4) as the first multidimensional SuFEx connector. SOF4 sits between the commercially mass‐produced gases SF6 and SO2F2, and like them, is readily synthesized on scale. Under SuFEx catalysis conditions
氟化硫(VI)交换(SuFEx)是基于点击化学的新型转换,可通过S VI集线器合成共价连接的模块。在这里,我们报告亚硫酰四氟化物(SOF 4)作为第一个多维SuFEx连接器。SOF 4位于商业化大量生产的气体SF 6和SO 2 F 2之间,并且像它们一样,很容易按比例合成。在SuFEx催化条件下,SOF 4可靠地找出伯氨基[R- NH 2 ],并通过四面亚氨基亚硫(VI)链接永久锚定:RN =(O =)S(F)2。侧链前手性二氟化物基团RN =(O =)SF 2又提供了另外两个SuFExable句柄,可以依次交换这些句柄以从四面体硫(VI)集线器创建3维共价偏离向量。
