Reactions of difluoroamino-radicals. Part II. Addition to propene, cis-but-2-ene, and trans-but-2-ene

Abstract

The kinetics of the addition of tetrafluorohydrazine to olefins in the gas phase, which yields vicinal bisdifluoroamines, can be described in terms of the mechanism: NF₂+ Of = NF₂Of*(1); NF₂Of*= NF₂+ Of (2); NF₂Of*+ Mol = NF₂Of + Mol (3); NF₂Of = NF₂+ Of (4); NF₂Of + NF₂= Of(NF₂)₂(5), where Of is an olefin, NF₂Of* is an activated radical, and Mol is an inert molecule. Values of k₁, k₂/k₃, and k₄/k₅ have been found between 61 and 118°, and the Arrhenius parameters calculated for propene and cis- and trans-but-2-ene.
