Reaktionsschritte

In a 100 ml apparatus, there were combined 11.6 g (0.1 mol) of Et3SiH, 11.5 g (0.1 mol) of MeSiHCl2, and 9.1 g (0.1 mol) of methallyl chloride. After heating to 50° C., the heat source was removed and 0.05 ml Pt catalyst solution added, causing an exothermic reaction to 83.5° C. in 4 min. The complete reaction was vacuum distilled, yielding 13.83 g (67.3%) of MeSiCl2CH2CHMeCH2Cl and 4.31 g (20.9%) of Et3SiCH2CHMeCH2Cl. This example shows that while MeSiHCl2 at the equimolar level promotes the reaction between Et3SiH and methallyl chloride, it also competes with Et3SiH, reducing the yield of Et3SiCH2CHMeCH2Cl.
