Abstract
Functionalized organosilicon compounds comprising at least one activated azo group of formula (I): [(G)SiO][(G)SiO][GSiO][SiO][(G)(G)(Z-CO—HN═NH—CO-A)SiO], for example a mixture of silane species of formula (i): (CHO)Si—(CH)—NH—CO—N═N—COOCH; with siloxane species of formulae: (20.1): [(CH)SiO] [(CHO){(CH)—NH—CO—N═N—COOCH} SiO] and (20.2): [(CH)SiO][(CHO) {(CH)—NH—CO—N═N—COOCH} SiO], are prepared from at least one hydrazino precursor (II) (—HN—NH—) of compound (I), by oxidizing the precursor (II) into an azo group for the compound (I) utilizing at least one oxidizing agent (Ox) and at least one vase (B) and also a supplementary reagent selected from among silanes of formula (III): (G DEG)4-p1Si (G)p1 [for example, (CH)(CHO)Si].
