実験手順: 1.0 mole of 3-chloropropyltriethoxysilane (Cl-PTES) and 1.1 moles of sodium azide were heated together in a 500 ml capacity three neck flask made of glass and equipped with reflux condenser and magnetic stirrer and in the presence of 5 mole percent of a catalyst on the basis of a mixture of tris(n-C8 to C10 alkyl)methyl ammonium chloride with stirring for 3 hours at 140° C. The rectification subsequently carried out thereon at reduced pressure gave the 3-azidopropyltriethoxysilane (N3 -PTES) in a yield of 95 weight percent. The N3 -PTES had the following properties: equipped with reflux condenser and magnetic stirrer

実験手順: To a solution of 3-chloropropyltriethoxysilane (2.31 g, 9.6 mmol) and tetrabutylamonium iodide (0.020 g, 0.05 mmol) in butanone (25 mL) was added sodium azide (3.120 g, 48 mmol) and the reaction mixture was heated under reflux for 50 h. Filtration over celite was followed by evaporation of the solvent under vacuum. The residue was dissolved in dichloromethane (150 mL) and then washed with water (2 times 20 mL). The organic phase was dried (NaSO4) and evaporated to give the desired product (1.9 g). the reaction mixture was heated under reflux for 50 h Filtration over celite was followed by evaporation of the solvent under vacuum The residue was dissolved in dichloromethane (150 mL) washed with water (2 times 20 mL) The organic phase was dried (NaSO4) evaporated
