S 98 Synthesis of novel perfluoroalkyl-containing polyethers [Text] / D. N. Bazhin, T. I. Gorbunova, A. Ya. Zapevalov, V. I. Saloutin // Journal of Fluorine Chemistry. - 2009. - Vol. 130, № 4. - P438-443 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The synthesis of iodo(perfluoroalkyl)epoxides by radical addition of perfluoroalkyl iodides to allyl glycidyl ether and 1,2-epoxydec-9-ene is described. Dehydroiodination of additional products upon treatment with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) gives unsaturated products. The use of Bu3SnH/Bz2O2 as a reduction reagent of iodo(perfluoroalkyl)allyl glycidyl ethers allows to save oxirane ring. Cationic polymerization of saturated or functional (with iodine or double bond) fluoroalkyl oxiranes under action of catalytic amount of BF3.Et2O proceeds only on epoxide group. In case of poly(9-iod-10-(perfluoroalkyl)-1,2-epoxyalkane) iodine atoms are removed by standard zinc reduction \\\\Expert2\\nbo\\Journal of Fluorine Chemistry\\2009, V. 130, P. 438.pdf |
