Procedure

1.0 mole of 2-chloroethyltriethoxysilane and 1.1 moles of sodium azide in 500 ml of acetone were heated in the presence of 3 mole percent of the catalyst described in Example 1 (a) for ten hours under intensive stirring and under reflux. After separation of the salt the subsequent distillation under reduced pressure gave the 2-azidoethyltriethoxysilane in a yield of 69 weight percent with the following characteristics:
