Ynol ethers are one of the most interesting functional groups for the preparation of more complex molecules and the development of new synthetic methodology.[1] In particular, tert- butyl ynol ethers are particularly desirable as precursors to ketenes by the liberation of isobutene on warming.[2] Although a number of ynol ethers have been prepared (mainly by halogenation and subsequent elimination of enol ethers, because the reaction of alkoxide ...
