Hydrogen Abstraction from Dimethyl Sulfide by Trifluoromethyl Radicals

Abstract

Additional data are presented for hydrogen abstraction from (CH₃)₂,S by CF₃ radicals

CF₃+(CH₃)₂S → CF₃H+CH₂SCH₂ (1)

leading to a revised value for the rate constant (k in cm³ mol^-1 s^-1, E in J mol^-1):

logk₁ = (11·83±0·06)-(26910±450)/19.16T

Combination of these results with thermochemical data gives a revised value of

logk^-1 = 11·9-61800/19·145T

for the rate constant of the reverse reaction.
