α,ο-Halohydrins and ο-acetylenic alcohols are protected as t-butyl ethers by reaction with isobutene and an acid catalyst : Amberlyst H-15. t-Butyl ethers are, in turn, cleaved to acetates by Ac2O and 10 percent FeCl3 in Et2O solvent.Under these mild conditions conjugated dieneic systems are neither destroyed nor isomerized.
