Data from: SnO2-SiO2 Mesoporous Composite: A Very Active Catalyst for Regioselective Synthesis of Aromatic Ketones with Unusual Catalytic Behavior

Attached file provides supplementary data for linked article.

Aromatic ketones (R-Ar-CO-') have been prepared directly through C-C bond formation using aromatics, aryl, and alkyl acid halides in a Friedel-Crafts reaction over a reusable and catalytically active ordered SnO2-SiO2 three-dimensional mesoporous composite (PS-4) catalyst, which was found to be superior to modified zeolites, functionalized MCM-41, and supported heteropolyacid catalysts.

研究以芳烃、芳基化合物与烷基酰卤为原料，通过傅-克反应（Friedel-Crafts reaction）直接构建碳-碳键，合成得到芳香酮类化合物（R-Ar-CO-）；所用催化剂为可重复使用且具备催化活性的有序二氧化锡-二氧化硅（SnO₂-SiO₂）三维介孔复合材料（PS-4），该催化剂的性能优于改性沸石、功能化MCM-41以及负载型杂多酸催化剂。
