4-Chlorobutylferrocene was synthesized from 4-ferrocenylbutanoic acid by typical reactions of NaBH4-I2-THF reduction and thionyl chloride chlorination

in stead of the traditional method with ferrocene and 4-chlorobutyryl chlorid as raw materials

in which NaBH4-I2-THF system replaces toxic zinc amalgam as reducing agent.(4-Ferrocene-butyl) dimethyl silane was perpared from dimethyl chlorosilane and format reagent which was produced by magnesium powder and 4-chlorobutyl ferrocene.The butacene with high yield

which was formed from hydrosilylation

was successfully obtained by reaction of (4-ferrocene-butyl) dimethyl silane and hydroxyl-terminated polybutadiene(HTPB) in the presence of the efficient and reusable platinum catalyst (silica-supported chitosan complex of chloroplatinic acid SiO2-CS-Pt).The structure of the polymer was characterized by 1H-NMR and FTIR.Thermal stability of the polymer was studied using TGA.This work also measured the rate of grafting and the hydroxyl value.The results show that the desired target product with the advanced initial decomposition temperature

increased thermal sensitivity

increased thermal stability and excellent catalytic performance was obtained.
