실험 절차

In a 100 ml apparatus, there were combined 7.1 g (0.075 mol) of Me2SiHCl, 8.7 g (0.075 mol) of Et3SiH and 5.7 g (0.075 mol) of allyl chloride. Pt catalyst solution was added (0.05 ml) at 34° C. Gentle heating caused a smooth exothermic reaction to 92° over 36 min. Vacuum distillation yielded 42.5% of Me2SiClCH2CH2CH2Cl and 4.8% of Et3SiCH2CH2CH2Cl. This example shows that Et3SiH at the equimolar level is an effective promoter for the reaction between Me2SiHCl and allyl chloride.
