Cyclic and bicyclic polyfluoro-alkanes and -alkenes

Saturnene Revealed: X‐ray Crystal Structure of D5d‐C60F20 Formed in Reactions of C60 with AxMFy Fluorinating Agents (A=Alkali Metal; M=3d Metal)

“…It is known that CoF 3 is a more active FA than MnF 3 . [16][17][18] In the present study, this difference is manifested in the FF products of C 60 fluorination under identical conditions: C 60 F 36 was formed primarily along with small amounts of C 60 F 18 and C 60 F 20 when MnF 3 was used, and C 60 F 38 and C 60 F 40 were formed primarily along with some C 60 F 36 when CoF 3 was used. It was also found that LiCoF 4 is a stronger FA than LiMnF 4 .…”

“…[9] One attractive feature of FFs that distinguishes them from most other FCMs is that they are molecular and in many cases have been isolated with 85 mol % purity or higher as single isomers with well-determined structures and well-determined, reproducible physicochemical properties. [10] These FFs include 13 C 60 F n compounds (n = 2, 4, 6, 8 (two isomers), 18,20,24,36 (three isomers), 38, 48) and several dozen fluorinated higher fullerenes and heterofullerenes. [10] For any FF to become a practical component of an FCM for a particular application, its efficient synthesis and purification must be possible.…”

“…The second group of FAs includes ternary salts containing Mn III and Co III . It is known that CoF 3 is a more active FA than MnF 3 16–18. In the present study, this difference is manifested in the FF products of C 60 fluorination under identical conditions: C 60 F 36 was formed primarily along with small amounts of C 60 F 18 and C 60 F 20 when MnF 3 was used, and C 60 F 38 and C 60 F 40 were formed primarily along with some C 60 F 36 when CoF 3 was used.…”

Atomic fluorine in cobalt trifluoride thermolysis

“…Cobalt trifluoride has been used for a long time, as a mild fluorinating reagent for the synthesis of organic fluoroderivatives [1,2]. Fluorination occurs on the surface of CoF 3 (s) particles to which organic molecules R have been supplied.…”

“…(2)): 2CoF 3 ðgÞ ! Co 2 F 6 ðgÞ (2) were established. In contrast, the thermal decomposition of CoF 3 (s) has not been investigated in detail.…”
