Abstract (en)
[origin: WO2018122511A1] The invention relates to the field of organic polysulphides, more particularly to a method for synthetising functionalised organic polysulphides of formula (I): R2-X-(NR1R7)C*H-(CH2)n-Sa-(CH2)n-C*H(NR1R7)-X-R2, in which the various substituents are as defined in the description, by reacting at least one compound of formula (II: G-(CH2)n-C*H(NR1R7)-X-R2, in which the various substituents are as defined in the description, with at least one inorganic polysulphide in the presence of at least one enzyme selected from the sulfhydrylases. The invention also relates to the functionalised organic polysulphides of formula (I) obtained by the method of the invention, and to their uses for lubrification, vulcanisation, catalyst sulphidisation and medicinal drug preparation.
