چکیده

The CF and CF3 1 fragment ion yield curves from C2F4 have been remeasured by photoionization mass spectrometry. Fits with appropriate model curves yield the appearance potentials AP0~CF3 /C2F4!513.72160.005 eV and AP0~CF /C2F4!513.77760.005 eV and an accurate difference in ionization potentials, IP~CF!2IP~CF3!50.05560.003 eV. With the existing photoelectron value IP~CF!59.1160.01 eV, this produces IP~CF3!59.05560.011 eV. The CF3 1

Mechanistic studies on the formation of trifluoromethyl sulfur pentafluoride, SF5CF3--a greenhouse gas.

The formation of SF5CF3(X1A'), through the radical-radical recombination of SF5(X2A1) and CF3(X2A1), was observed for the first time in low-temperature sulfur hexafluoride-carbon tetrafluoride matrices at 12 K via infrared spectroscopy upon irradiation of the ices with energetic electrons. The nu1 fundamentals of the SF5(X2A1) and CF3(X2A1) radicals were monitored at 857 and 1110 cm-1, respecti...

Trifluoromethyl-substituted tetrathiafulvalenes

A series of tetrathiafulvalenes functionalized with one or two trifluoromethyl electron-withdrawing groups (EWG) is obtained by phosphite coupling involving CF3-substituted 1,3-dithiole-2-one derivatives. The relative effects of the EWG such as CF3, CO2Me and CN on the TTF core were investigated from a combination of structural, electrochemical, spectrochemical and theoretical investigations. E...

Determination of rate constants for trifluoromethyl radical addition to various alkenes via a practical method.

A simple and practical method for the determination of rate constants for trifluoromethyl radical addition to various alkenes by applying competition kinetics is introduced. In the kinetic experiments the trifluoromethyl radicals are generated in situ from a commercially available hypervalent-iodine-CF3 reagent (Togni-reagent) by SET-reduction with TEMPONa in the presence of TEMPO and a π-accep...

Biocatalytic trifluoromethylation of unprotected phenols

Organofluorine compounds have become important building blocks for a broad range of advanced materials, polymers, agrochemicals, and increasingly for pharmaceuticals. Despite tremendous progress within the area of fluorination chemistry, methods for the direct introduction of fluoroalkyl-groups into organic molecules without prefunctionalization are still highly desired. Here we present a conce...

Generation of the CF3 radical from trifluoromethylsulfonium triflate and its trifluoromethylation of styrenes.

The CF(3) radical was generated from the reaction of S-(trifluoromethyl)diphenylsulfonium triflate with Na(2)S(2)O(4) or HOCH(2)SO(2)Na under suitable conditions without further reduction. Based on this, a method for the synthesis of α-trifluoromethylated ketones has been successfully developed.
