Telomerization of ethylene with bromoform

Conclusions

  1. 1.

    We were the first to telomerize ethylene with bromoform, initiated either by benzoyl peroxide or by the systems: Fe(CO)5+DMF and Fe(CO)5+hexametapol.

  2. 2.

    In the studied reaction the CHBr3 reacts mainly at the C-Br bond to give the telomer homologs CHBr2(CH2CH2)Br (n = 1, 2).

  3. 3.

    As side products we isolated 1,1,1,3-tetrabromopropane and 1,3,3,5-tetrabromopentane, whose formation is apparently related to the partial reaction of the CHBr3 at the C-H bond.
