A novel proton-conducting monomer 4-[(3-(trimethoxysilyl)propoxy)methyl]-1H- 1,2,3-triazole(Ⅲ) was synthesized using chloromethyl pivalate as main materials by azide substitution, cycloaddition and Williamsen synthesis. The effects o f reaction temperature, reaction time, molar ratio of raw materials and ammount of catalysts on the yield were investigated by othorganol test and single factor experiments. The optimum reaction conditions for preparing azidomethyl pivalate(Ⅰ) were as follows: n(sodium azide ) :n( chloromethyl pivalate) =1.5:1, reaction time 20 h ,reaction temperature 78 ℃ and for preparing 2,2-dimethyl propionic acid-(4-hydroxymethyl-1,2,3 triazol-1-yl)methyl ester(Ⅱ) were: n(propargyl alcohol): n(Ⅰ)=1.3:1, reaction temperature 50 ℃, reaction time 24 h and n(CuSO4•5H2O):n(ascorbic acid):n (Ⅰ)=0.02:0.1:1. The yield of the product(Ⅲ) was 63.9%.The structures of the compounds synthesized were characterized by the methods of FTIR, 1H NMR and 13C NMR .
