Procedure

A mixture of 578.6 g 3,4-dichlorobutyl triethoxysilane (2.0 moles) and 750 ml toluene is combined at reflux temperature within 2 hours with 92.0 g molten sodium in a heatable (approximately 130° C.) dropping funnel. In order to complete the reaction, the mixture is subsequently agitated for 30 minutes more at 120° C. After the workup already described in b), 417.3 g crude product =95.4% of theory are obtained which yield 366.0 g 3-butenyl triethoxysilane as a main fraction in the subsequent vacuum fractionation, corresponding to 83.7% of theory.
