ABSTRACT Chromium-pillared montmorillonite (Cr-PLM) could be synthesized and efficiently utilized for styrene oxide transformations. The target aldehyde product could be quantitatively achieved from the isomerization of styrene oxide by using 10 wt% of Cr-PLM under reflux temperature for 15 min. The acetonide product could be achieved in excellent yield from the reaction of styrene oxide and acetone
摘要 铬柱撑蒙脱石 (Cr-PLM) 可以合成并有效地用于氧化苯乙烯的转化。通过使用10wt%的Cr-PLM在回流温度下15分钟,氧化苯乙烯的异构化可以定量地获得目标醛产物。通过使用 10 wt% 的 Cr-PLM 在室温下反应 20 分钟,可以从氧化苯乙烯和丙酮的反应中以优异的收率获得丙酮化物产物。催化剂可以回收和重复使用至少五次而不会损失活性。图形概要
