报道了一种具有2D P6mm六方结构的周期性介孔氯化硅（PMSCl）作为一种高效的、可循环使用的催化剂，用于多种酚类化合物通过Pechmann反应合成相应的香豆素。反应在无溶剂条件下以良好至优异的产率进行。
Periodic mesoporous silica chloride (PMSCl) with 2D P6mm hexagonal structure which can be prepared by a simple procedure is reported to act as an efficient and recyclable catalyst for the conversion of a variety of phenols into their corresponding coumarins through Pechmann reaction. The reactions were conducted under solvent-free conditions in good to excellent yields.
