Reaction Conditions:

with chloro-trimethyl-silane at 20; for 6 h;

Steps:

Allyloxytrimethylsilane (11).
A mixture of allyl alcohol (100 g, 1.172 mol), hexamethyldisilazane (138.94 g, 0.86 mol) and few drops of chlorotrimethylsilane was stirred at room temperature for 6 h. The product was purified by distillation.
