| Studies on polyhaloalkanes Ⅰ.Radical addition of polyfluoroalkyl iodides to diethyl allylphosphonate | |
| 摘 要： | Radical addition of polyfluoroalkyl iodides to the C=C double bond of diethyl allylphos-phonate was carried out in CH_2Cl_2-H_2O two-phase medium in the presence of sodium dithioniteto give dicthyl 3-polyfluoroalkyl-2-iodopropylphosphonates(3)in excellent yields.Compounds 3were then converted to diethyl polyfluoroalkanephosphonates(4)by zinc-reduction,Thus a facilemethod for preparing polyfluoroalkanephosphonates is realized. |
