Reaktionsschritte

In a 100 ml apparatus, there were combined 7.1 g (0.075 mol) of Me2SiHCl, 10.2 g (0.075 mol) of Cl3SiH, and 5.7 g (0.075 mol) of allyl chloride. Pt catalyst solution (0.01 ml) was added at 33° C., causing an exothermic reaction to 47° C. in 7 min. VPC analysis 14 min. later showed a complete reaction. Vacuum distillation yielded 60.4% Cl3SiCH2CH2CH2Cl and 8.6% Me2SiClCH2CH2CH2Cl. This example shows that Me2SiHCl is an effective promoter for the reaction of Cl3SiH with allyl chloride at the equimolar level.
