Reactions of ketone acetals with iodosilane equivalents were studied. Treatment of alkanone ethylene acetals with a 1:2 mixture of Et2NSiMe3 and Mel afforded 2-siloxyethyl enol ethers in good yield. Benzophenone ethylene acetal underwent I deprotection with the iodosilane equivalents, giving benzophenone.
