Product 1

HCID 536631743-Azidopropylmethyldiethoxysilane

Conditions

Temperature: 140 °C

Procedure

1.0 mole of 3-chloropropylmethyldiethoxysilane and 1.1 moles of sodium azide were heated in the presence of 5 mole percent of the catalyst described in Example 1 (a) for three hours under stirring at 140° C. After the distillation under reduced pressure there was obtained the 3-azidopropylmethyldiethoxysilane in a yield of 94 weight percent.
