Synthesis and study of physicochemical properties of hexa(1,1,3-trihydrotetrafluoropropyloxo)uranium

Hexa(1,1,3-trihydrotetrafluoropropyloxo)uranium with 45-50% yield is synthesized at low temperature. The compound prepared is sensible to moisture, soluble in pentane, chloroform, benzene, stable when heated in vacuum up to 200 deg. For the compound temperature dependence of vapour pressure in the range from -32 up to -15 deg C is investigated. At 20 deg the vapour pressure constitutes 0.2 ± 0.03 Tor. The compound is charcterized by the NMR-, IR-, and UV-spectroscopy methods. The values of heat and entropy of sublimation are given
