Beschreibungen/Notizen

• [Display omitted] ► We present an innovative outlet for the valorisation of metal contaminated biomass produced in phytoextraction technologies. ► We show the interest of metal hyperaccumulator plants in supported Lewis acid catalysis. ► They are novel tools for Green Friedel–Crafts alkylation and acylation. ► Efficient and eco-friendly syntheses of functionalised aromatic derivatives are made possible. The main goal of this work was to prove the interest of metal hyperaccumulator plants in supported Lewis acid catalysis. Friedel–Crafts alkylation and acylation reveal the great catalytic activity of different plant extracts. This approach is a green solution with chemical benefits including high yield, excellent regioselectivity, small amounts of catalyst, mild conditions and concrete perspectives towards the depletion of mineral resources. The results also constitute an incentive for the development of phytoextraction programs on metal-bearing soils.
