Procedure

1.0 mole of 3-chloropropyltris(methoxyethoxy)-silane and 1.1 moles of sodium azide in 500 ml of acetonitrile were heated in the presence of 5 mole percent of the catalyst described in Example 1 (a) for eight hours under reflux and stirring. After separation of the salt the subsequent distillation under reduced pressure gave the 3-azidopropyltris(methoxyethoxy)silane in a yield of 84 weight percent with the following characteristics:
