Abstract
The CH3OCH2+ ion reacts with NH3 and with primary and secondary amines R2NH with the elimination of CH3OH to form the protonated imines R2NC H+. Proton transfer and methyl cation transfer, although exothermic, a re not major channels. Elimination of CH3OH is also observed with C2H5 OH to form C2H5OCH+. No reaction is observed with HCN, while methyl ca tion transfer to form CH3CNCH3+ is the main channel with CH3CN. The re activity of the CH3CHOH+ isomer is different, with fast proton transfe r to CH3CN and NH3. With CH3CN, a fast three-body association channel is also observed.
