Reaction of E-1,4-Poly(2-Triethylsilyl-1,3-Butadiene) with Iodine Monochloride

摘要

Addition of iodine monochloride to E-1,4-poly(2- triethylsilyl-1,3-butadiene) (I) followed by treatment with potassium fluoride dihydrate yields a copolymer comprised of E and z-1,4(2-iodo-1,3-butadiene) (E and Z-II) units and Z-1,4-(2-chloro-1,3-butadiene) (Z-III) units. The mechanism of this reaction is discussed. The product copolymer has been characterized by 1H and 13C NMR, IR, UV, GPC, TGA and elemental analysis. Keywords: Electrophilic substitution; Reprints.
