A sulfonicacidfunctionalized metal–organic framework (S-IRMOF-3) has been synthesized by dropwise addition of chlorosulfonic acid (0.5 mL) in IRMOF-3 (1 g) containing 20 mL of CHCl3 at 0 °C under simple stirring. The catalyst was applied in Knoevenagel condensation of various aromatic and hetero-aromatic aldehydes forming acrylonitrile derivatives. The catalyst was characterized thoroughly by using
磺酸功能化金属有机骨架 (S-IRMOF-3) 通过在简单搅拌下在 0 °C 下将氯磺酸 (0.5 mL) 滴加到含有 20 mL CHCl 3的 IRMOF-3 (1 g) 中合成。该催化剂应用于各种芳香醛和杂芳香醛的 Knoevenagel 缩合反应,形成丙烯腈衍生物。采用FT-IR、XRD、13 C MAS NMR、SEM、EDX、元素映射、TEM、BET、NH 3 -TPD和TGA/DTA技术对催化剂进行了全面表征。在 FT-IR 光谱中,在 1694 cm -1、1254–769 cm -1和 1033 cm -1处存在特征带,在 XRD 图案中存在 2 θ ≃ 6.7° 和 9.8° 以及δ= 31.79, 39.55, 129.61, 131.46 (4C, CH), 133.54, 140.07 (2C), 167.71, 171.47 ppm (2C, 2C O) 在固态13
