In this communication, we established an interesting palladium-catalyzed carbonylation protocol for the intramolecular cyclization of azoarenes. With Mo(CO)6 as the solid CO source and through C(sp2)?H bond activation, a series of azoarenes were transformed into the corresponding 2-arylindazolones in moderate to good yields. Notably, not only symmetrical azoarenes, but also unsymmetrical substrates underwent the reaction with excellent regioselectivity.

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
