regioselective, and convergent method for the ring expansion and rearrangement of 1‐sulfonyl‐1,2,3‐triazoles under rhodium(II)‐catalyzed conditions is described. These denitrogenative reactions form substituted enaminone and olefin‐based products (see scheme). The enaminone products can be further functionalized to give various heterocycles and ketonederivatives, thus rendering the sulfonyl triazole traceless
