The Suzuki coupling Knoevenagel condensation one-pot synthesis of boronic acids/esters, (hetero)aromatic bromo aldehydes and methylene active compounds is a highly practical consecutive three-component process to provide substance libraries with 60 donor-π-bridge-acceptor molecules, i.e., merocyanines in a broader sense, in moderate to excellent yield. As already seen with the naked eye, a broad variation
Suzuki 偶联 Knoevenagel 缩合一锅法合成硼酸/酯、(杂)芳族溴醛和亚甲基活性化合物是一种非常实用的连续三组分工艺,可提供具有 60 个供体-π-桥-受体分子的物质库,即,更广泛意义上的部花青,产量中等至极好。正如肉眼所见,使用这种实用的合成工具可以实现光学特性的广泛变化。更系统地,在绘制光学带隙与近亲系列氧化还原活性系统的第一氧化电位时的相关性分析提供了线性相关性,并且通过扩展,两个参数图(氧化电位和发射最大值)与光学带隙平面相关性。
