Abstract
<jats:p>A new reagent, 2‐azidoethane‐1‐sulfonylfluoride (ASF), was synthesized from 2‐chloroethane‐1‐sulfonyl fluoride in 50g‐scale with 87 % yield. This novel reagent possesses two selectively clickable functionalities to be used for both CuAAC and SuFEx click reactions. The application of this reagent ASF to the construction of a class of novel 1,2,3‐triazole derived S(VI)‐F analogs was achieved in a quick, efficient and atom‐economical manner. Orthogonally clickable construction of a new class of dendrimers was also accomplished.</jats:p>
