    • The invention relates to producing an organo alcoxydialkylsilane by a method which consists in introducing by pouring an alcanol in a dialkylhalogenosilane omega-halogenalkyl + an organic solvent (s) phase mixture and in removing a halogen acid formed by entrainment with the aid of said organic solvent(s) phase and is characterised, in particular (i) by selecting a particular phase of solvent(s), for example based on cyclohexane, (2i) by carrying out an alcanol introduction mode which makes it possible to control the drawing off the halogen acid formed during reaction and by (3i) controlling the halogen acid quantity in a reaction medium. The thus obtained dialkylhalogenosilane omega-halogenalkyl is usable, in particular as an initial product for preparing organosilisic sulphur-containing compounds of general formula (IV) by a sulfidising reaction carried out on a alkali metal polysulfur.
