摘要

季铵氢氧化物树脂因其作为固定碱的有效性而得到广泛认可，并经常作为商品化学品用于阴离子交换应用。然而，尽管它们很容易获得，但对其特性进行化学控制却具有挑战性，这阻碍了将它们用作固体碱催化剂的研发工作。本研究探讨了实现聚苯乙烯树脂高功能性的关键合成因素。以市场上可买到的树脂为基准，以连续流亨利反应为模型系统，我们探索并评估了新合成的树脂催化剂，以最大限度地提高它们的基本催化活性。

Structure-Directed Quaternary Ammonium Hydroxide Resins: High-Performance Heterogeneous Base Catalysts for Continuous-Flow Carbon–Carbon Bond-Forming Reactions

Quaternary ammonium hydroxide resins are widely recognized for their effectiveness as immobilized bases and are frequently utilized as commodity chemicals for anion-exchange applications. However, despite their accessibility, chemically controlling their properties has proven challenging, hindering research and development efforts toward their use as solid base catalysts. This study investigates the synthetic factors that are crucial for achieving high functional performance in polystyrene resins. Using commercially available resin as a benchmark and the continuous-flow Henry reaction as a model system, we explore and evaluate newly synthesized resin catalysts to maximize their basic catalytic activity.
