Compositions of manganese accumulating plants.

Compositions of certain manganese accumulating plants

The use, after heat treatment, of manganese accumulating plants for carrying out chemical reactions.

Use of certain manganese-accumulating plants for carrying out organic chemistry reactions

Disclosed is a method for reducing organic compounds using catalysts containing nickel (0) from metal hyperaccumulator plants. The method can be implemented in a green manner and is advantageous compared to methods using the known catalysts.

Use of certain transition metal hyperaccumulator plants for reducing organic compounds in a green manner

Disclosed is an adduct between a Lewis acid, preferably aluminum trichloride, iron trichloride, or zinc dichloride, and a hydrosilane;&#x2014;a method for preparing same; and a method for for reducing, particularly, an aldehyde, a ketone, an &#x3b1;,&#x3b2;-unsaturated ketone, an imine, or an &#x3b1;,&#x3b2;-unsaturated imine.

Hydrosilane/Lewis acid adduct, particularly aluminum, iron, and zinc, method for preparing same, and use of said same in reactions for reducing carbonyl derivatives

Disclosed is a process for preparing a product of formula I: wherein the reaction is catalyzed both by thiamine or a thiamine salt and by ascorbic acid in a form which is free or salified or an organic acid salt of an alkaline metal, preferably sodium acetate, potassium tartrate, sodium succinate, or a reductone, preferably 2-hydroxypropanedial or 2,3-dihydroxycyclopent-2-ene-1-one in an organic solvent.

Process for preparing synthesis intermediates using products of natural origin and use of the intermediates obtained

A composition derived from the acid treatment of ashes obtained after heat treatment of selected plants or plant material is provided. The selected plants accumulate metal from the platinum group (platinoids). The compositions can be used to produce catalysts for performing various organic synthesis reactions.
