reported. The developed methodology tolerates various functional groups and allows the synthesis of diverse unsymmetrical azophenols under mild conditions in good to excellent yields. A complementary procedure was also investigated by in situ generation of PIFA. This study represents the first general method for the synthesis of o-hydroxyazobenzenes starting from simple azoarenes.

meta/ortho-Selective CAr-H (di)alkylation reactions of azoarenes with various types of alkyl bromides have been achieved via [Ru(p-cymene)Cl2]2 catalyzed ortho-metalation. Especially, dual meta-alkylations of azoarene and reductions offered an attractive strategy...
