In the quest for more sustainable chemical processes, we devised a technique using electro-organocatalysis to synthesize bis--diketone compounds via Knoevenagel condensation of benzaldehyde and dimedone. Our approach involves a modified electrode fabricated anchoring L-proline onto a carbon fiber paper electrode supported by poly-3,4-diaminobenzoic acid (PDABA), which enhances efficiency in addition to the simple catalyst separation from the reaction mixture in heterogeneous catalysis. The electrochemical and surface topographical studies for the fabricated electrode were carried out, revealing high efficiency in comparison to the bare carbon fiber paper electrode. This electrochemical reaction operates under mild conditions utilizing lithium perchlorate and acetonitrile, yielding high amounts of the desired product. This study showcases a promising pathway for producing valuable organic compounds in an environmentally friendly manner, marking a significant stride forward in sustainable synthesis practices.

固定化脯氨酸基电有机催化剂用于通过 Knoevenagel 缩合反应合成双-β-二酮


为了寻求更可持续的化学工艺，我们设计了一种使用电有机催化通过苯甲醛和双甲酮的诺文纳格尔缩合来合成双二酮化合物的技术。我们的方法涉及一种将 L-脯氨酸锚定到由聚 3,4-二氨基苯甲酸 (PDABA) 支撑的碳纤维纸电极上的修饰电极，除了在多相催化中从反应混合物中简单分离催化剂之外，还提高了效率。对所制造的电极进行了电化学和表面形貌研究，结果表明与裸碳纤维纸电极相比具有更高的效率。该电化学反应利用高氯酸锂和乙腈在温和条件下进行，产生大量所需产物。这项研究展示了一种以环境友好的方式生产有价值的有机化合物的有前途的途径，标志着可持续合成实践的重大进步。
