Method for preparing 3, 3, 3-trifluoropropyne through gas-phase dehydrohalogenation

The invention discloses a method for preparing 3, 3, 3-trifluoropropyne through gas-phase dehydrohalogenation. The method comprises the following steps: taking 1-halogen-3, 3, 3-trifluoropropene or/and 2-halogen-3, 3, 3-trifluoropropene (halogen = F or Cl or Br or I) as a raw material, and carrying out gas-phase dehydrohalogenation reaction in the presence of a catalyst to obtain the 3, 3, 3-trifluoropropyne. The method disclosed by the invention is mainly used for producing the 3, 3, 3-trifluoropropyne in a gas-phase continuous circulation manner at a high conversion rate and high selectivity.

METHOD

A method for activating a catalyst comprises the steps of: a) optionally drying the catalyst at a temperature of from 100°C to 400°C; b) treating the catalyst with a composition comprising HF at a temperature of from 0°C to about 500°C; c) treating the catalyst with a composition comprising an oxidant and optionally HF at a temperature of from about 100°C to about 500°C.

Selective Copper Complex-Catalyzed Hydrodefluorination of Fluoroalkenes and Allyl Fluorides: A Tale of Two Mechanisms

The transition to more economically friendly small-chain fluorinated groups is leading to a resurgence in the synthesis and reactivity of fluoroalkenes. One versatile method to obtain a variety of commercially relevant hydrofluoroalkenes involves the catalytic hydrodefluorination (HDF) of fluoroalkenes using silanes. In this work it is shown that copper hydride complexes of tertiary phosphorus ligands (L) can be tuned to achieve selective multiple HDF of fluoroalkenes. In one example, HDF of the hexafluoropropene dimer affords a single isomer of heptafluoro-2-methylpentene in which five fluorines have been selectively replaced with hydrogens. DFT computational studies suggest a distinct HDF mechanisms for L2CuH (bidentate or bulky monodentate phosphines) and L3CuH (small cone angle monodentate phosphines) catalysts, allowing for stereocontrol of the HDF of trifluoroethylene.
