发明名称 PREPARATION OF FUNCTIONALIZED ORGANOSILICON COMPOUNDS IN A BIPHASE MEDIUM
摘要 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.
