실험 절차

In a 100 ml apparatus, there were combined 8.6 g (0.075 mol) of MeSiHCl2, 7.1 g (0.075 mol) of Me2SiHCl, and 5.7 g (0.075 mol) of allyl chloride. Pt catalyst solution (0.01 ml) was added at 37° C., followed by heating up to 45° C. over 1 hr. Vacuum distillation yielded 31.3% of MeSiCl2CH2CH2CH2Cl and 22.6% of Me2SiClCH2CH2CH2Cl. This example shows that neither Me2SiHCl nor MeSiHCl2 is a very effective promoter at the equimolar level for reactions of the other with allyl chloride.
