New rhodium(II)‐catalyzed or thermally induced intramolecular alkoxy group migration of N‐sulfonyl‐1,2,3‐triazoles has been developed, affording divergent synthesis of 1,2‐dihydroisoquinoline and 1‐indanone derivatives according to different conditions. N‐Sulfonyl keteneimine is the key intermediate for the synthesis of dihydroisoquinoline, whereas the aza‐vinyl carbene intermediate results in the
