Functionalized organosilicon compounds (I), including at least one azo-activated structural unit, are prepared by: A. reacting at least one silane precursor (IV) with at least one hydrazo-precursor compound (V) to obtain hydrazine precursors (II) of such organosilicon compounds and B. oxidizing the hydrazine group of the precursors (II) to obtain precursors of the compounds (I), employing an oxidizer (NaOCl) and a base (NaOH), the oxidation being carried out in a biphase aqueous/organic medium, with the pH of the aqueous phase ranging from 3 to 11, such oxidation B being carried out directly in the reaction medium obtained from step A and containing the precursors (II), without isolating these precursors.
功能化有机硅化合物(I),包括至少一个偶氮活化的结构单元,通过以下步骤制备:A. 将至少一个硅烷前体(IV)与至少一个叠氮前体化合物(V)反应,以获得此类有机硅化合物的叠氮前体(II),并且B. 氧化前体(II)的叠氮基以获得化合物(I)的前体,使用氧化剂(NaOCl)和碱(NaOH),氧化在双相水/有机介质中进行,水相的pH范围为3至11,这种氧化B直接在从步骤A获得的反应介质中进行,并且包含前体(II),而无需分离这些前体。
