Abstract: The invention relates to the use of a hydroperoxy alcohol-type compound, or a 1,2,4-trioxane compound thereof, as an antimicrobial agent, making it possible for it to be used in various applications and in particular as a preservative and/or to improve the antimicrobial properties of at least one preservative, to modulate the skin microbiota, in the treatment or prevention of diseases affecting the skin, the mucous membrane and/or skin appendages or even to cleanse, sanitise, disinfect and/or sterilise a surface other than the skin, skin appendages and mucous membranes, in particular a hard surface or a textile. It also relates to a composition comprising such a compound. In addition to its antimicrobial properties, the aforementioned compound has good safety and emollient properties, making it particularly suitable for cosmetic use.

Abstract: The present invention relates to a process for preparing hydroperoxy alcohols using hydrogen peroxide as an oxidant in a solvent selected from water-soluble carboxylic acids, in the presence of a metallic mixed oxide heterogeneous catalyst. It also pertains to the use of this catalyst in the synthesis of hydroperoxy alcohols.

Abstract: The present invention relates to a process for synthesizing hydroperoxy alcohols by perhydrolysis of epoxides, using an aqueous solution of hydrogen peroxide, in the presence of a catalyst consisting of phosphotungstic acid.

Abstract: The present invention relates to a method for oxidative cleavage of a substrate consisting of at least one functionalised or non-functionalised linear olefin, in particular a mono- or polyunsaturated aliphatic carboxylic acid, or one of the esters thereof, or at least one non-functionalised cyclic olefin, using hydrogen peroxide, in the presence of a metal catalyst which consists of at least one onium halooxodiperoxometallate. It also relates to a novel catalyst consisting of a specific onium halooxodiperoxometallate which can be used, in particular, in said method.

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

Abstract: 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.

Abstract: Disclosed is an adduct between a Lewis acid, preferably aluminum trichloride, iron trichloride, or zinc dichloride, and a hydrosilane;—a method for preparing same; and a method for for reducing, particularly, an aldehyde, a ketone, an ?,?-unsaturated ketone, an imine, or an ?,?-unsaturated imine.

Abstract: 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.

Abstract: 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.
