Disproportionation reactions between alkyl and fluoroalkyl radicals. III. A reassessment of Δ values for CF_<i>y</i>H(_3−<i>y</i>) radicals (<i>y</i> = 1,2,3) with C₂H₅ radicals

Abstract

Abstract New determinations of the disproportionation and combination ratios between CF 2 H and C 2 H 5 radicals yield (the hydrogen acceptor radical is given first) Δ(CF 2 H, C 2 H 5 ) = 0.068 ± 0.008, and Δ(C 2 H 5 , CF 2 H) = 0.37 ± 0.01. A reevaluation of the existing data on CFH 2 and CF 3 radicals leads to the following recommended values, Δ(CFH 2 , C 2 H 5 ) = 0.038 ± 0.006, and Δ(CF 3 , C 2 H 5 ) = 0.11 = ± 0.02.
