Ethene-1,1-disulfonyl difluoride (EDSF) represents a novel SuFEx connector hub. Here, we demonstrate the [2+2] cycloaddition reaction of EDSF with aryl acetylenes, which rapidly and regioselectively generates unique 1,1-bissulfonylfluoride substituted cyclobutenes. Moreover, these products can selectively undergo SuFEx reactions with phenols, highlighting their potential for constructing complex molecular
