Infrared multiphoton dissociation of CBrF2CHClF, CBrF2CHBrF, and CBrClFCBrF2 in a molecular beam

Dynamics and mechanisms of infrared multiphoton dissociation of CBrF2CHClF, CBrF2CHBrF, and CBrClFCBrF2 have been studied using a photofragmentation translational spectroscopy.All molecules dissoociated through C-Br bond rupture reactions.At high laser fluence, the halogenated ethyl radicals produced by the primary dissociation reactions dissociated through carbon-halogen bond ruptures.Center-of-mass product translational energy distributions for the C-Br and C-Cl bond ruptures of all halogenated ethanes and ethyl radicals studied are essentially consistent with those calculated by Rice-Ramsperger-Kassel-Marcus (RRKM) theory.This indicates that there exists essentially no exit channel barrier on the potential energy surface for the C-Br or C-Cl bond rupture of the halogenated ethanes and ethyl radicals.

High-vacuum pyrolysis of 1,1,1-trifluoro-2-bromo-2-chloroethane. IR spectrum of 1,1,1-trifluoro-2-chloroethyl radical in an argon matrix

The products of high-vacuum pyrolysis of 1,1,1-trifluoro-2-bromo-2-chloroethane were studied by matrix IR spectroscopy. The decomposition of 1,1,1-trifluoro-2-bromo-2-chloroethane was shown to occur predominantly via two directions: to form the 1,1,1-trifluoro-2-chloroethyl radical and trifluoromethylcarbene isomerizing to trifluoroethylene. The CF3CHCl radical has been detected in the matrix for the first time. The bands observed in the IR spectrum were calculated by the quantum-chemical B3LYP/6-311G(d,p) method and assigned to normal vibrations of the radical.

Telomerization of perfluoropoly(oxamethylene iodides) with trifluoroethylene

Radical telomerization of perfluoropoly(oxamethylene iodides) with trifluoroethylene was studied. Based on the 1H and 19F NMR spectroscopic data, the pathways for olefin addition to the iodide in the initial and subsequent stages were examined.

Selective liquid-phase hydrodechlorination of chlorotrifluoroethylene over palladium-supported catalysts: Activity and deactivation

Liquid-phase hydrodechlorination of chlorotrifluoroethylene (CTFE) to trifluoroethylene (TrFE) with molecular hydrogen was studied over palladium-supported catalysts. BaSO4, Al2O3 and activated carbon (AC) were used as supports, respectively. The results showed that the Pd/AC catalysts exhibit higher activity than Pd/BaSO4 and Pd/Al2O3. The treatment of activated carbon with HNO 3 led to a considerable increase of surface functional groups containing oxygen atoms, which resulted in a higher dispersion of palladium on the supports and enhancement of catalytic activity. The stability of the catalyst was investigated, one reason for the inhibition was the accumulation of NaCl on the surface of Pd/AC that blocks the pores of carbon support. The activity of Pd/AC could partially recovered by washing with water. The other irreversible deactivation of the catalyst are from the change of particle size and the pore structure, leaching of Pd, a decrease of BET surface area and Pd surface area of Pd/AC catalyst.

The invention relates to a synthetic method of ethyl 4, 4-difluoro-3-oxo-2-piperidine-1-methylene butyrate. The synthetic method comprises the following steps: 1, carrying out a condensation reactionon difluoroacetyl fluoride and 3-(1-piperidyl)-ethyl acrylate to generate 4, 4-difluoro-3-oxo-2-piperidine-1-yl methylene ethyl butyrate and hydrogen fluoride, and 2, carrying out a reaction on the hydrogen fluoride generated in the step 1 and trichloroethylene under the action of a fluorination catalyst to generate trifluoroethylene and hydrogen chloride, and 3, reacting the trifluoroethylene generated in the step 2 with oxygen under the action of a complex catalyst to generate difluoroacetyl fluoride, and recycling the difluoroacetyl fluoride generated in the step 3 as a reactant in the step1. According to the synthetic method of the ethyl 4, 4-difluoro-3oxo-2-piperidine-1-methylene butyrate, the raw materials are simple and easy to obtain, the atom utilization rate is high, and the production safety is high.

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.
