Abstract 2,4-Dibromophenyl benzoate (3) was synthesized via Steglich esterification. The derivatives of 2, 4-dibromophenyl benzoate (3) with electron withdrawing and donating aryl-boronic acids were prepared with good yields via palladium catalyzed Suzuki Miyaura reaction. DFT calculations were also implemented on the newly synthesized ester products to probe into their electronic structure and reactivity
摘要 通过 Steglich 酯化反应合成了 2,4-二溴苯基苯甲酸酯 (3)。通过钯催化的 Suzuki Miyaura 反应以良好的收率制备了具有吸电子和给体芳基硼酸的 2, 4-二溴苯基苯甲酸酯 (3) 衍生物。还对新合成的酯产品进行了 DFT 计算,以探究它们的电子结构和反应性描述符。根据 DFT 研究,化合物 6c 显示出最大的反应性,而 4 显示出最大的稳定性。此外,超极化值表明合成的化合物具有作为中等分子非线性光学(NLO)材料的潜力。
