Abstract FeCl3 impregnated Montmorillonite K10 was found to catalyze the Friedel-Craftsbenzylation of arenes. Monobenzylation, with the para isomer predominating, was achieved with trace amounts of dibenzylated product.

The replacement of liquid acid catalyst by solid acids for the Friedel-Crafts reaction of aromatic alkylation is a challenging task. Mixed oxide possessing spinel structures were found to catalyze the Friedel-Craftbenzylation of arenes. It was found that the reaction was very fast at 80 °C, hence the reaction was studied with respect to more substrate. The significant point was even at this temperature
用固体酸代替液体酸催化剂用于芳族烷基化的傅克反应是一项具有挑战性的任务。发现具有尖晶石结构的混合氧化物催化芳烃的傅-克苄基化。发现反应在 80 °C 时非常快,因此研究了更多底物的反应。重要的一点是即使在该温度下也实现了以对位异构体为主的单苄基化。采用共沉淀法制备混合氧化物,并采用XRD技术对其进行表征。
