Procedure
Sodium azide (1.5 equivalent) in 4 ml of sodium hydrogen phosphate and hydrogen chloride buffer (14.4 g or Na2HPO4 to 4.4 mil conc HCl in 1 liter of distilled water) per gram of azide is added dropwise to a stirred 50 percent solution of triethoxysilylhexane sulfonyl chloride in methylene chloride containing 1 percent Aliquat 336. The mixture is stirred at room temperature for thirty minutes after the addition is complete. The layers are separated. The methylene chloride layer is washed with a saturated salt solution, dried over magnesium sulfate and the methylene chloride is evaporated. Ninety percent solids of a light yellow liquid triethoxysilylhexane sulfonyl azide of about 90 percent purity are obtained.
