Reaction Conditions

Reaction Steps

A mixture of Et3SiH (10.5 g, 0.09 mol) and methallyl chloride (8.2 g, 0.09 mol) was combined in a 150 ml apparatus and 0.05 ml Pt catalyst solution added, followed by heating at reflux (115° C.) for 50 hr. Additional Pt catalyst solution (0.025 ml) was added at 40 hr. The incomplete reaction was distilled, yielding 4.98 g (36.8%) of Et3SiCl and 3.48 g (18.7%) of Et3SiCH2CHMeCH2Cl. This example shows that the unpromoted reaction of Et3SiH with methallyl chloride is very slow and endothermic.
