Wakeshima, Ikuko published the artcileSynthesis of β-diketone and β-keto ester complexes of yttrium(III), barium(II) and copper(II), COA of Formula: 0, the publication is Nippon Kagaku Kaishi (1992), 619-26, database is CAplus.
Synthesis of highly pure acetylacetone (Hacac), dipivaloylmethane (Hdpm), and Et acetoacetate (Hetac) chelates of Y(III), Ba(II), and Cu(II) was investigated. The chelates were synthesized by the reaction of the ligands with anhydrous YCl3 (in the presence of amine), Ba metal, or anhydrous Cu(OAc)2 using anhydrous solvents under dry atm. Anhydrous Y chelates were synthesized by using Et3N as dehydrochlorinating agent. High purity of metal chelates (Y, Ba, Cu) of Hdpm and Cu chelates of Hacac and Hetac isolated in this work was confirmed by IR and 1H NMR spectra in addition to elemental anal. Association and relative hydrolyzability of metal chelates are discussed according to the results of the 1H NMR, IR, and mass spectral measurement, the solubility, and the observation during the experiment
