The CH oxidative amination of (Z)‐1‐allylidene‐2‐arylhydrazines with 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO)/N‐bromosuccinimide (NBS) provides highly substituted pyrazoles with 100 % regioselectivity in moderate to good yields. These protocols are effective at room temperature and offer a route for the construction of the target five membered heterocycles.
