Process for the preparation of glicidiloxialquilalcoxisilanos of general formula (I) (R ") O-CnH2nSi (OR) 3 (I) wherein the groups R independently represent a linear or branched alkyl having 1 to 4 carbon atoms , n equals 1, 2, 3, 4, 5, 6, 7 or 8 and R "represents an H2C (O) CH- or H2C (O) CHCH 2, by reacting (i) an alkene functionalization of the general formula (II) (R ") O-CnH2n-1 (II), wherein R" represents an H2C (O) CH- or H2C (O) CHCH 2, n is equal to 1, 2, 3, 4 , 5, 6, 7 or 8, with (ii) at least one hidrogenoalcoxisilano of the general formula (III) HSi (oR) 3 (III) wherein the groups R independently represent a linear or branched alkyl with 1 to 4 carbon atoms in the presence of (iii) at least one homogeneous catalyst series catalysts Speier or Karstedt, (iv) at least one solvent and / or at least one diluent, and (v) at least one promoter acidic series monocarboxylic acids and dica rboxílicos, wherein - the components (i) olefin and (ii) hidrogenoalcoxisilano are used in a molar ratio of 1.8 to 1.0: 1.0, - the catalyst (iii) the olefin component (i) employed in a molar ratio of 1: 1,000,000 to 1: 25,000, - the catalyst (iii) and promoter (v) are used in a molar ratio of 1: 250 to 1: 25,000, and - the catalyst (iii) and the promoter (v) are diluted together in a solvent and / or diluent.
