摘　　要：应用红外光谱技术研究了在乙酸锌催化作用下1,5-萘二胺与碳酸二甲酯甲氧基羰基化反应机理.结果表明,二水合乙酸锌只有失去两个结晶水变成无水乙酸锌后才能产生催化活性.无水乙酸锌与1,5-萘二胺形成一个新的配位络合物,该配位络合物是一个适宜的亲核试剂,能与碳酸二甲酯进行亲核反应,生成1,5-萘二胺的甲氧基羰基化产物.在无水乙酸锌与1,5-萘二胺形成配位络合物的过程中,无水乙酸锌的结构从双齿型转变成单齿型.The methoxycarbonylation mechanism of 1,5-naphthalene diamine with dimethyl carbonate catalyzed by zinc acetate was investigated by Fourier transform infrared spectroscopy. Zinc acetate dihydrate was not active for the reaction until it changed into anhydrous zinc acetate by losing the crystal water. Anhydrous zinc acetate activated 1,5-naphthalene diamine by the formation of a new zinc complex. The new complex was a suitable nucleophilic reagent that could react with dimethyl carbonate to produce a methoxycarbonylation compound. When the complex of anhydrous zinc acetate with 1,5-naphthalene diamine was formed, the anhydrous zinc acetate changed from a bidentate ligand to a unidentate ligand.
