Abstract

The kinetics of gas‐phase reaction of CH~3~CF~2~I with HI were studied from 496 to 549K and have been shown to be consistent with the following mechanism:

A least squares treatment of the data gave

where θ = 2.303 RT kcal/mole. The observed activation energy E~1~ was combined with E~2~ = 0 ± 1 kcal/mole to yield

The result, combined with data for several CI bond dissociation energies, leads us to conclude that the C(sp^3^)I bond is relatively insensitive to F for H substitution and that the C(sp^2^)–I bond has considerable double‐bond character.
