The N-acyliminium ion intermediates generated from α-alkoxycarbamates in the presence of Lewis acids were for the First time detected by 1 H and 13C NMR. It was confirmed that there is an equilibrium between the starting carbamate and the intermediate and that the equilibrium is highly dependent upon a Lewis acid. By using the saturation transfer method, the rate constant for the formation of the intermediate was obtained. NOE experiments revealed that ((4-methylphenyl)methylene)methyl(methoxycarbonyl)ammonium methyltrifluoroborate 6 has E-geometry.

α-Silyl group activates carbamates toward electrochemical oxidation which results in facile cleavage of carbon-silicon bond and regioselective introduction of methanol at α-carbon.
