Four fluorinated cesium beta-diketonates, Cs (CF3COCHCOCF3)(Cs (hfac)), Cs (CF3COCHCOCH3)(Cs (tfac)), Cs (OH2)((Me) 3CCOCHCOCF3)(Cs (OH2)(ptac)), and Cs (OH2)(PhCOCHCOCF3)(Cs (OH2)(btfac)), were synthesized by interaction of the corresponding beta-diketone and Cs2CO3 in Et2O. The formation of Сs (CF3C (OH) 2CH2C (OH) 2CF3)(CF3COO) or Cs (CF3C (OH) 2CH2COCH3)(tfac) was shown to be dependent ...
