A new method for the synthesis of 1-arylindazolones and 2-arylindazolones from N′-aryl-2-halobenzohydrazides promoted by KOt-Bu was developed. The difference of 2-halogen substituent exerted a significant effect on the distribution of the products. Two di

An efficient and convenient access to 1-substituted indazol-3-ones 2 has been achieved throughout the intramolecular C-N bond formations of 2-chloro-benzoic acid-N′-aryl and alkyl-hydrazides employing 0.5 mol% of cuprous (I) iodide and 20 mol% of l-prolin
