Summary
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 2-1,4-(2-chloro-1,3-butadiene) (Z-III) units. The mechanism of this reaction is discussed. The product copolymer has been characterized by1H and13C NMR, IR, UV, GPC, TGA and elemental analysis.
