<p>The invention concerns the preparation of halogenated monoorganoxysilanes, of formula (I), said compounds being useful as synthesis intermediate in organic chemistry. Said method for preparing monoorganoxysilanes consists in: using as starting product halogenoalkylsilanes of the (CH3)2SiCl2 type and in substituting the silicon with a radical bearing a divalent unit bound to an electrophilic reactive group capable of reacting with at least an appropriate nucleophilic agent to form a functionalised monoorganoxysilane of formula (II) with, for example: R1 = C1-C4 alkyl; R?2, R3 = C¿1-C6 alkyl; B = C1-C10 alkylene; m = 1 or 2; Hal = halogen; W = amino, mercapto, (organosilyl)-organopolythio radical.</p> |
