Titanium-catalyzed C-F activation of fluoroalkenes

(Figure Presented) Detox: Air-stable titanocene difluoride efficiently catalyzes the chemoselective hydrodefluorination of fluoroalkenes at room temperature leading to hydrofluoroalkenes in high yields (see scheme: Cp = cyclopentadienyl). This is a rare example of the catalyzed conversion of fluoroalkenes into less-fluorinated compounds, which have a lower climatic impact, and is a potential method for breaking down toxic perfluoroalkenes.

Gallium Hydrides and O/N-Donors as Tunable Systems in C?F Bond Activation

The gallium hydrides (iBu)2GaH (1 a), LiGaH4 (1 b) and Me3N?GaH3 (1 c) hydrodefluorinate vinylic and aromatic C?F bonds when O and N donor molecules are present. 1 b exhibits the highest reactivity. Quantitative conversion to the hydrodefluorination (HDF) products could be observed for hexafluoropropene and 1,1,3,3,3-pentafluoropropene, 94 % conversion of pentafluoropyridine and 49 % of octafluorotoluene. Whereas for the HDF with 1 b high conversions are observed when catalytic amounts of O donor molecules are added, for 1 a, the addition of N donor molecules lead to higher conversions. The E/Z selectivity of the HDF of 1,1,3,3,3-pentafluoropropene is donor-dependent. DFT studies show that HDF proceeds in this case via the gallium hydride dimer–donor species and a hydrometallation/elimination sequence. Selectivities are sensitive to the choice of donor, as the right donor can lead to an on/off switching during catalysis, that is, the hydrometallation step is accelerated by the presence of a donor, but the donor dissociates prior to elimination, allowing the inherently more selective donorless gallium systems to determine the selectivity.

Activation of pentafluoropropane isomers at a nanoscopic aluminum chlorofluoride: Hydrodefluorination versus dehydrofluorination

The hydrofluorocarbon 245 isomers, 1,1,1,3,3-pentafluoropropane, 1,1,1,2,2- pentafluoropropane, and 1,1,1,2,3-pentafluoro-propane (HFC-245fa, HFC-245cb, and HFC-245eb) were activated through C-F bond activations using aluminium chlorofluoride (ACF) as a catalyst. The addition of the hydrogen source Et3SiH is necessary for the activation of the secondary and tertiary C-F bonds. Multiple C-F bond activations such as hydrodefluorinations and dehydrofluorinations were observed, followed by hydroarylation and Friedel-Crafts-type reactions under mild conditions.

Preparation method of Z-1-halogen-3, 3, 3-trifluoropropene

The invention discloses a preparation method of Z-1-halogen-3, 3, 3-trifluoropropene. The preparation method comprises the following steps: in the presence of a block catalyst, E-1-halogen-3, 3, 3-trifluoropropene is subjected to a gas phase isomerization reaction in a tubular reactor to obtain Z-1-halogen-3, 3, 3-trifluoropropene, and halogen is fluorine or chlorine. According to the preparation method, 1, 1, 1, 3, 3-pentachloropropane is used as an initial raw material, Z-1-chloro-3, 3, 3-trifluoropropene or Z-1, 3, 3, 3-tetrafluoropropene secondary product is prepared through a gas-phase fluorination reaction and an isomerization reaction, the materials which are not completely reacted are independently circulated through a gas-phase independent circulation process so that the initial raw materials can be almost completely converted into the target product, and finally, the target product is extracted from a process system, and thus liquid waste and waste gas are not generated, and green production is realized.
