The complexation reaction of phenyl 2-pyridyl ketoxime with some transition and heavy metal ions Co2+, Ni2+, Zn2+, Pb2+, Fe2+, Fe3+, Cr3+ and La2+ has been studied potentiometrically. The reactions of phenyl(2-pyridyl)ketone oxime, with nickel(II) sulfate hexahydrate, in the absence of an external base, have been investigated.
The E-isomer crystallises from EtOH (charcoal). It isomerizes to the Z-isomer on melting or in boiling o-xylene, and crystallises from EtOH or cyclohexanol with m 166-168o. [Beilstein 21 H 330, 21 III/IV 4120, 21/8 V 568.]
