Abstract
The chemoselective allylation of acetals catalyzed by TMS triflate proceeds smoothly at room temperature in ionic liquids to provide the corresponding homoallyl ethers in good yield. The ionic liquids can be recycled and are therefore an alternative to dichloromethane, which is the standard solvent for allylations.
