Synthesis of Binuclear Antimony Complexes with Tetraketonate Ligands

Resumo

Reactions of tetraphenylantimony bromide with sodium salts of 3,8-dioxodeca-4,6-diene-5,6-diol and 2,2,9,9-tetramethyl-3,8-dioxodeca-4,6-diene-5,6-diol at various molar ratios of the reactants have been studied. Irrespective of the molar ratio, binuclear chelate complexes Ph₄Sb[OC(R)CHC(O)(O)CCH(R)CO]SbPh₄ are formed. The structures of the resulting complexes were established by the methods of IR and NMR spectroscopy.
