Kozminykh V.О., Kirillova E.A., Vinogradov A.N., Mukovoz P.P., Scherbakov Yu.V., Mozgunova E.M., Golotsvan A.V., Kozminykh E.N. 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 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.
