実験手順

In a 100 ml apparatus, there as combined 13.6 g (0.1 mol) of Cl3SiH, 9.1 g (0.1 mol) of methallyl chloride, and 11.5 g (0.1 mol) of MeSiHCl2, followed by 0.05 ml Pt catalyst solution at 21° C. Gentle heating caused an exothermic reaction to 52° C. in 22 min. The complete reaction was vacuum distilled, yielding 14.14 g (68.8%) of MeSiCl2CH2CHMeCH2Cl and 4.86 g (21.5%) of Cl3SiCH2CHMeCH2Cl. This example indicates that at the equimolar level, neither Cl3SiH nor MeSiHCl2 is an effective promoter for reactions of the other with methallyl chloride.
