Abstract

Sulfur(VI) fluoride exchange (SuFEx) is a new family of click chemistry based transformations that enable the synthesis of covalently linked modules via S(VI) hubs. Here we report thionyl tetrafluoride (SOF(4) ) as the first multidimensional SuFEx connector. SOF(4) sits between the commercially mass-produced gases SF(6) and SO(2) F(2) , and like them, is readily synthesized on scale. Under SuFEx catalysis conditions, SOF(4) reliably seeks out primary amino groups [R-NH(2) ] and becomes permanently anchored via a tetrahedral iminosulfur(VI) link: R-N=(O=)S(F)(2) . The pendant, prochiral difluoride groups R-N=(O=)SF(2) , in turn, offer two further SuFExable handles, which can be sequentially exchanged to create 3-dimensional covalent departure vectors from the tetrahedral sulfur(VI) hub.
