Abstract

The reactions of bismuth trichloride (BiCl3) with Î²-diketone (acetylacetone; Hacac, benzoylacetone; Hbzac, dibenzoylmethane; Hdbzm, dipivaloylmethane; Hdpm) in the presence of sodium cyanate and additives (tetramethylurea, THF, 15-crown-5, triethylammonium chloride) in methanol/benzene solution yielded the corresponding pure tris (Î²-diketonato) bismuth (III) complexes. THF was the most effective additive in the reaction of BiCl3 with Hdbzm. The solubility of the isolated bismuth (III) complexes for aprotic organic solvents (benzene, THF, dichloromethane and hexane) and methanol was examined. The characterization of the isolated bismuth (III) complexes was carried out by means of IR 1H,-NMR, 13C-NMR, MS and TG measurements.
