An efficient and divergent synthesis of N-arylbenzimidazoles and N-arylindazoles from arylamino oximes based on reaction conditions selection was developed. The synthesis was approached by treating oximes with BTC and the chemoselectivity was regulated by the amount of Et3N. This switchable N–N and N–C bond formation process features mild reaction conditions, simple execution, high chemoselectivity and broad substrate scope.

The title compounds 10, 23 are formed in low yields on treatment of 2,2'-organylimino-bisbenzoic acid esters 8 with methyllithium, but in high yields in the intramolecular ester condensation with sodium hydride of triarylamines 12, containing o-acetyl-, a
