Participants

Conditions

Temperature: 80 °C

Procedure

800 g of 4-bromo-1-butene were reacted with 15% excess of dimethylethoxysilane (939 ml). In a 2 l reactor 0.5 g of Ru3(CO)12 and 800 ml of 4-bromo-1-butene were brought under nitrogen and 939 ml of dimethylethoxysilane were added under nitrogen and the mixture was brought at 65° C. After 0.5 h the bath temperature was raised to 80° C. and the mixture was allowed to react overnight. After distillation 1329 g (93.7%) of 4-bromobutyl-dimethyl-ethoxysilane were isolated.
