中文摘要：

二元羧酸取代类化合物常被选为桥联配体,用于制备多孔的金属有机骨架材料.以对羟基苯甲酸甲酯为原料,在无水丙酮中与K2CO3和2-溴丙酸甲酯反应得到相应的二甲酯,该酯在强碱水解后再酸化得到产物2-（4-羧基苯氧基）丙酸.通过2步反应得到一个二元羧酸类刚柔配体：2-（4-羧基苯氧基）丙酸,产率为78%.产物经熔点（212~214℃）、元素分析（w（C）=56.98%;w（H）=4.36%）、红外光谱（1 726 vs;1 665 vs;1 505 m）、核磁共振谱（δ1.53 CH3,δ4.97 CH,δ7.88 Ar-H,δ6.96 Ar-H）和质谱（m/z210、209、137、93）表征,结果和产物一致.

英文摘要：

Substituted dicarboxylate compounds were often selected as bridge-linking ligands to make porous metal organic frameworks（MOFs） materials.2-（4-Methoxycarbonylatophenoxy）methyl propionate from the reaction of methyl p-hydroxybenzoate with potassium carbonate and methyl 2-bromopropanoate in acetone was obtained.The 2-（4-carboxylatophenoxy）propionic acid-a rigid-flexible dicarboxylate ligand was synthesized by hydrolysis and acidation of methyl 2-bromopropanoate in acetone with the yield of 78% by the two-step reactions.The ligand was characterized by melting point（212~214℃）,elemental analysis（w（C）=56.98%;w（H）=4.36%）,FT-IR（1726 vs;1665 vs;1505m）,1H NMR spectra（δ1.53 CH3,δ4.97 CH,δ7.88 Ar-H,δ6.96 Ar-H） and mass spectra（m/z 210,209,137 and 93）.
