Lithium perchlorate diethyl ether/methyl triflate catalyzed transfer of silicon from oxygen to carbon in silyl ketene (thio) acetals
Migration of a trimethylsilyl group from oxygen to the alpha-carbon (retro- [1,3]-Brook rearrangement) in silyl ketene acetals is catalyzed by LPDE/methyl triflate under mild conditions.
