Acetals react with allyltrimethylsilane in the presence of a catalytic amount of sulfonic acids to give the corresponding homoallylic ethers in high yields. The scope of the reaction is broad and both aromatic as well as aliphatic acetals can readily be used.

The synthesis of homoallyl ethers from various acetals and a cyclic ketal with allyltrimethylsilane catalyzed by aluminum bromide in the presence of trimethylaluminum as a desiccant is described. We found that the addition of a catalytic amount of copper(I) bromide accelerates the allylation reactions to afford the homoallyl ether derivatives in good to excellent yield.
