ON THE DIOXIMINE COMPLEXES OF TRANSITION METALS. PART XCIV. NEW RHODIUM(III) COMPLEXES WITH α-SUBSTITUTED ALIPHATIC AND ALICYCLIC OXIMES

Abstract

Some chelating agents were obtained by condensation of the α-keto-oximes diacetyl-monoxime, methyl-isopropyl-2,3-dione-monoxime (2) and 1,2,3-cyclohexane trione dioxime (1,3) with semicarbazide and thiosemicarbazide. The formation of rhodium(III) chelates with these reagents was studied spectrophotometrically in a wide pH-range using the continuous variation method. Some derivatives were proposed for the analytical determination of this metal.
