Synthesis and rearrangement of 3-(N-indolino)-1-aryltriazenes to 5-arylazoindoles
Indoline couples with aryldiazonium chlorides at pH 5 to give-3-(N-indolino)-1-aryltriazenes which undergo rearrangement in the presence of chloranil to give 5-arylazoindoles.Formation of the triazene is not only dependent on the pH but also on the nature of the substituent on the phenyl ring of the aryldiazonium ion.
