A new approach was developed for carbon–carbon bond formation via Henry reaction using a mixture of Mg(OH)₂ and CeCO₃OH (MgCe‐HDC). The MgCe‐HDC was synthesized using a co‐precipitation method and was characterized by SEM, XRD, FTIR, TGA‐DTA, and AFM. The effects of temperature, solvent, and the amount of catalyst were investigated to find the optimum reaction conditions. The highest yield of nitroaldol product, 92 %, was achieved over the reusable solid base catalyst in solvent‐free conditions at 20 °C.

Mg（OH）2和CeCO3OH杂化复合物的合成及表征及其对亨利反应的改进活性

开发了一种新的方法，该方法使用Mg（OH）₂和CeCO ₃ OH（MgCe-HDC）的混合物通过亨利反应形成碳-碳键。MgCe-HDC采用共沉淀法合成，并用SEM，XRD，FTIR，TGA-DTA和AFM表征。研究了温度，溶剂和催化剂用量的影响，以找到最佳反应条件。在20°C的无溶剂条件下，与可重复使用的固体碱催化剂相比，硝基醛产品的最高收率为92％。
