SYNTHESIS AND PECULIARITIES OF STRUCTURE OF SODIUM ENOLATES AND ESTERS OF 2, 4, 6, 7, 9-PENTAOXODECANOIC ACIDS ^{[№ 4 ' 2010]}
Sodium enolates and corresponding ethyl and methyl esters of 2, 6, 7-trihydroxy-4,9-dioxo-2,5,7-decatrienoic acids are got with ester condensation of Klizen. The features of the structure of synthesized polyketids with joined α-, β-dioxolinks are discussed in this article.

METAL DERIVATIVES OF ρ-π-ELECTRON DONATING POLYCARBONYL SYSTEMS WITH CLOSED α- AND β-DIOXO FRAGMENTS. PART 3. SYNTHESIS AND STRUCTURE OF METAL(II)CHELATES OF 4-OXODERIVATIVES OF 2-HYDROXY-2ALKENOATE ETHERS ^{[№ 4 ' 2009]}
Metal-exchange reaction of metal(II) salts in water solutions with sodium enolates of 4-oxoderivatives of 2-hydroxy-2-alkenoate ethers (LNa), synthesized by the Claisen condensation of methylenecarbonyl compounds (methyl ketones or ethyl acetate) with diethyl oxalate at basic conditions, leads to O,O’-coordinated metal-1,3-diketonate complexes, i.e. metal(II)chelates (L₂Met) composed on oxoalkenoate bidentate ligands. The structure peculiarities of synthesized β-diketonates are discussed. Presented are data, additional to preceding papers, about synthesis, structure and properties of functionalized 1,3-dicarbonyl anion metal derivatives.
