  将均相催化材料固定在合适的多相载体上是最大限度地减少均相和多相催化剂的缺点并结合其优点的最新策略之一。然而，基于物理吸附的固定化由于其温度以及溶剂依赖性的高度可逆性质而无法达到目的。在目前的工作中，通过将苯-1,3-二磺酸作为活性催化材料在微米级二氧化硅表面化学吸附，开发了一种新型催化材料二氧化硅键合双(硫酸氢)苯(SiO 2 -BHSB)。新合成的催化材料的合成、结构、纯度、热稳定性和酸强度通过固态CP-MAS等适当的分析技术得到证实13 C-NMR、CP-MAS 29 Si-NMR、FT-IR、EDX、TGA、DSC 和体积研究。开发了一种用于合成高度取代的 4 H -吡喃支架的高效且环境友好的催化方案，其中观察到少量的 SiO 2 -BHSB (3 mol%) 足以促进乙酰乙酸烷基酯、丙二腈和结构多样的醛可在水基溶剂中提供良好至优异的 4 H-吡喃衍生物收率。合成的 4 H的结构-吡
