Claims21
A method for implementing an organic synthesis reaction, comprising the following steps:
- a) preparing a composition containing at least one polymetallic agent, metals of which are selected from metals originating from a plant or a part of a plant, said composition containing less than 10% by weight of organic matter according to the following steps:
- i) dehydrating a plant or a part of a plant, said plant or said part of said plant belonging to a genus selected from the group consisting of Alyxia, Azolla, Beauprea, Beaupreopsis, Bridelia, Crotalaria, Dicranopteris, Dipteris, Eugenia, Gleichenia, Gossia, Macadamia, Maytenus, Pinus, Phytolacca, Spermacone, Stenocarpus, Virotia and Grevillea, that has accumulated manganese (Mn) and at least a metal selected from the group consisting of magnesium (Mg), iron (Fe), calcium (Ca) and aluminum (Al), and obtaining a dried plant or dried part of said plant;
- ii) grinding the dried plant or dried part of said plant obtained from step i), and obtaining a grinded mixture;
- iii) thermally treating the grinded mixture obtained for step ii) and obtaining the composition containing at least one polymetallic agent, said composition comprising Mn and at least a metal selected from the group consisting of Mg, Fe, Ca and Al;
- b) adding to a reaction mixture the composition obtained from step a);
- and
- c) implementing an organic synthesis reaction selected from the group consisting of radical oxidations, epoxidations, oxidations of alcohols located in an alpha position of a heterocyclic or carbocyclic aromatic group or of a double bond, oxidizing cleavage of polyols, oxidation of benzamines, and oxidizing aromatic dehydrogenation of unsaturated and/or conjugated cyclic derivatives optionally comprising a heteroatom, wherein the composition is a catalyst for the organic synthesis reaction.
