| titleOfInvention | Method of preparing organosilicon compounds |
| abstract | The field of the invention is that of the synthesis of compounds functionalized organosilicon compounds comprising at least one activated azo group, formula (I): [(G0) 3 SiO1 / 2] m [(G0) 2 SiO2 / 2] n [G0SiO3 / 2] o [SiO4 / 2] p [(G2) a (G1) a '(Z-CO-HN = NH-CO-A) SiO (3-a-a') / 2] This process consists in At least one precursor (II) hydrazino (-HN-NH-) of the compound (I) oxidizing the precursor (II) to an azo group specific to the compound (I), using an oxidizing system comprising at least one oxidant (Ox) and at least one base (B), this method being characterized in that 1) Ox is selected from oxidants capable of oxidizing a hydrazine function in azo function, excluding or not N-bromosuccinimide (NBS), preferably from halogens, halogenated derivatives and mixtures thereof, and more preferably still in the group comprising: bromine, tert-butyl hypochlorite, acid trichloroisocyanuric acid, chlorine and mixtures thereof; 2) and / or Ox (optionally B) is (are) implemented in stoichiometric quantities by relation to the precursor (II); 3) and / or the organosilicon compounds are subjected (I) thus prepared for a post-purification treatment aimed at eliminating in particular any unwanted residues of the base B used; with the condition that, in the event that the NBS is not excluded, the feature 1) is combined with characteristic 2) and / or feature 3). The invention also relates to pure compounds (I) likely to be obtained by this process. |
