Sažetak
This work presents preparation and thermal characterization of three novel organomercurials: Hg2(CF3COCHCOCF3)2- 2- (CF3COCCOCF3) 2(CF3C(OH)2CH2C(OH)2CF3) (I), Hg2(CF3COCHCOCF3)2- 2- (CF3COCCOCF3) (II) and Hg2(CH3COCHCOCF3)2- 2-(CH3COCCOCF3) (III) which means that they contain at least one direct mercury-to-carbon bond among the carbonyl groups of  -diketone molecules which are capable for chelating of metal ions. IR- spectra support the conclusion that mercury is most probably bound to the  -carbon of fluorinated derivatives of acetylacetone and is not chelated through oxygen in any of the isolated compounds. The thermal decomposition of mercurated hexafluoro- and trifluoroacetylacetone in nitrogen occurs in a few steps. Each step was identified and studied by simultaneous DTA/TGA analyzer. On the basis of dynamic heating experiments by TGA applying Flynn-Wall method the activation energy for each of them was determined.
