Background: SO3H-functionalized zeolite-Y was prepared and used as a catalyst for the synthesis of 2-aryl-N-benzimidazole-4-thiazolidinones and tri-substituted imidazoles at ambient conditions.

Objective: The goals of this catalytic method include excellent yields and high purity, inexpensive procedure and ease of product isolation, the use of nontoxic and heterogeneous acid catalyst, shorter reaction times and milder conditions.

Materials and Methods: NMR spectra were recorded on Brucker spectrophotometer using Me4Si as internal standard. Mass spectra were recorded on an Agilent Technology 5975C VL MSD with tripe-axis detector. FTIR spectra were obtained with KBr disc on a galaxy series FT-IR 5000 spectrometer. The surface morphology of nanostructures was analyzed by FE-SEM (EVO LS 10, Zeiss, Carl Zeiss, Germany). BET analysis were measured at 196 °C by a Japan Belsorb II system after the samples were vacuum dried at 150°C overnight.

Results: The NSZ was characterized by FT-IR, FESEM, EDX, XRF, and BET. The catalytic activity of NSZ was investigated for synthesis of 1,3-tiazolidin-4-ones in H2O/Acetone at room temperature. Moreover, NSZ was used for synthesis of tri-substituted imidazoles at 60 °C via solvent-free condensation. Different kinds of aromatic aldehydes were converted to the corresponding of products with good to excellent yields.

Conclusion: Sulfonated zeolite-Y was as an efficient catalyst for the preparation of N-benzimidazole-2-aryl-1,3- thiazolidin-4-ones and 2,4,5-triaryl-1H-imidazoles. High reaction rates, elimination toxic solvent, simple experimental procedure and reusability of the catalyst are the important features of this protocol.

材料与方法：以Me4Si为内标，在Brucker分光光度计上记录NMR光谱。在具有三轴检测器的Agilent Technology 5975C VL MSD上记录质谱。FTIR光谱是使用KBr盘在银河系列FT-IR 5000光谱仪上获得的。通过FE-SEM（EVO LS 10，蔡司，卡尔蔡司，德国）分析纳米结构的表面形态。将样品在150°C真空干燥过夜后，通过Japan Belsorb II系统在196°C下测量BET分析。

结果：NSZ的特征在于FT-IR，FESEM，EDX，XRF和BET。研究了NSZ在室温下于H2O /丙酮中合成1,3-噻唑烷-4-酮的催化活性。此外，NSZ还用于在60°C下通过无溶剂缩合合成三取代的咪唑。将不同种类的芳族醛以良好或优异的产率转化为相应的产物。

结论：磺化沸石Y是制备N-苯并咪唑-2-芳基-1,3-噻唑烷-4-酮和2,4,5-三芳基-1H-咪唑的有效催化剂。高反应速率，消除有毒溶剂，简单的实验程序和催化剂的可重复使用性是该方案的重要特征。
