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

Diversity Oriented Clicking (DOC) is a unified click‐approach for the modular synthesis of lead‐like structures through application of the wide family of click transformations. DOC evolved from the concept of achieving “diversity with ease” , by combining classic C−C π‐bond click chemistry with recent developments in connective SuFEx‐technologies. We showcase 2‐Substituted‐Alkynyl‐1‐Sulfonyl Fluorides
