実験手順

In a 100 ml apparatus, there were combined 11.6 g (0.1 mol) of Et3SiH, 8.4 g (0.1 mol) of 3,3-dimethyl-1-butene, and 13.6 g (0.1 mol) of Cl3SiH. Pt Catalyst solution was added (0.05 ml) at 24° C., causing a rapid exothermic reaction to 57° C. in 4 min. Vacuum distillation yielded 1.82 g (8.3%) of Cl3SiCH2CH2CMe3 and 11.95 g (59.8%) of Et3SiCH2CH2CMe3. This example shows that Cl3SiH is an effective promoter at the equimolar level for the reaction between Et3SiH and 3,3-dimethyl-1-butene.
