• improvement in time and yield in comparison to other solid catalysts. The heterogeneous catalyst can be reused at least three times without a significant loss in activity.

• made their employment an attractive choice. Recently, we have successfully employed a Fe-Al-MCM-41 catalyst in a Friedel–Crafts-type hydroarylation reaction of styrenes [33]. The catalyst demonstrated high yields of products with good selectivities within a short reaction time under “open flask
