Conclusions

  1. 1.

    Rearrangement of ĊH2CCl3 radicals with 1,2-migration of Cl has been studied at temperatures ranging from 25 to −60°C by ESR spin trap methods. ĊH2CCl3 radicals were generated by reacting BrCH2CCl2 with (C2H5)3Si; the unrearranged radicals were identified as spin-adducts with 2-methyl-2-nitroso-3-butanone, and the rearranged ClCH2ĊCl2 radicals as adducts with nitrosodurol.

  2. 2.

    The reaction of (C2H5)3Si withα,α,α-trichloro-ω-bromoalkanes proceeds selectively through detachment of Br and Cl atoms. This same reaction has been studied in other polychloroalkanes.
