PURPOSE OF THE ABSTRACTAdvances in green catalysis have promoted the development of ecological catalysis encountered in most of themain transformations of organic chemistry. Taking advantage of the remarkable capacity of certain plants tohyperaccumulate transition metals into shoots or roots, we have addressed the direct use of metals derived fromcontaminated plant wastes as supported Lewis acid catalysts, coupling agents, oxidising and reducing catalysts ingreen chemistry. This approach constituted the first example of chemical catalyst based on phytotechnologies.Here, we will show that the concept can be extended to common and abundant plant species that are surprisinglyappropriated for chemical catalysis. We will present that Salix, Willow, Birch, Plane and Linden trees can be usedto produce bio-based and original Lewis acid catalysts. The catalytic potential of these species will be illustratedthrough two representative transformations, acetalisation and oxidative esterification.More generally, these novel polymetallic catalytic ecomaterials will be used to generate bio-based molecules andchemicals for future applications and will serve as a bridge between ecological and chemical catalysis.
