When dialkoxymethanes are dissolved in fluorosulfonic acid at -70 deg.C, the alkoxycarbenium ions RCH2O=CH2(1+) and the corresponding alcohols RCH2OH are formed.If the temperature is raised to -20 deg.C a 1,3-hydride shift occurs in the ions, leading to the formation of the more stable RCH=OCH3(1+) cations.The alternative path to the formation of the latter by intermolecular hydride transfer is not realized.A degenerate 1,3-hydride shift occurs in the methoxymethyl cation at 40 deg.C.
