Abstract
The products of high-vacuum pyrolysis of 1,1,1-trifluoro-2-bromo-2-chloroet hane were studied by matrix IR spectroscopy. The decomposition of 1,1,1-tri fluoro-2-bromo2-chloroethane was shown to occur predominantly via two direc tions: to form the 1,1,1-trifluoro-2-chloroethyl radical and trifluoromethy lcarbene isomerizing to trifluoroethylene. The CF3CHCl radical has been det ected in the matrix for the first time. The bands observed in the IR spectr um were calculated by the quantum-chemical B3LYP/6-311G(d,p) method and ass igned to normal vibrations of the radical.
