Abstract:	Extractive ability of 1-substituted 3-methylpyrazol-5-ones (LH) is studied. From acidic chloride complexes, ionic thallium(III) associates (LH₂)[TlCl₄] are extracted; from trichloroacetate, coordination scandium complexes Sc(LH)₄(CCl₃COO)₃; and from ammine, copper(II) complexes CuL₂. The extractive ability decreases in the order R = C₇H₁₅ > C₆H₁₃ > C₅H₁₁ > C₆H₅ > C₄H₉.__________Translated from Zhurnal Obshchei Khimii, Vol. 75, No. 2, 2005, pp. 326–330.Original Russian Text Copyright © 2005 by Lesnov, Sazonova, Pavlov.
