| Abstract: | ![]()
2-(2-Pyridylazo)phenol and 4-(2-pyridylazo)phenol were prepared by the condensation of 2-hydrazinopyridine with o- and p-benzoquinone. Their metal complexing properties were studied and compared with those of 4-(2-pyridylazo)-resorcinol. The roles played in chelation by the two hydroxyl groups of the latter compound are discussed. |
