Abstract
With chloromethyl pivalate as the main raw material,a novel proton-conducting monomer 4-{[3-(trimethoxysilyl)propoxy]methyl}-1H-1,2,3-triazole(Ⅲ) was synthesized through a series of reactions of azide substitution,cycloaddition and Williamsen synthesis.The effects of reaction temperature,reaction time,molar ratio of raw materials and amount of catalysts on the yield were investigated by orthogonal 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 ℃.Those 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 synthesized compounds were characterized by means of FTIR,1HNMR and 13CNMR.
