Reactions of [CH3]+ and [CD3]+ with alcohols

The reactions of [CH3]+ and [CD3]+ with a number of C1 to C5 alcohols were studied at approximately thermal energies (0.1 eV) using a tandem Dempster ion cyclotron resonance mass spectrometer. Branching ratios obtained under single collision conditions are reported for [CH3]+ and [CD3]+ with methanol, perdeutero methanol, ethanol, allyl alcohol, 1‐propanol, 2‐propanol, perdeutero‐2‐propanol, 1‐butanol, 2‐butanol, t‐butanol, cyclopentanol and 1‐pentanol. The results are examined in terms of the mechanism of reactions and indicate that upon progression to larger alcohols, the formation of a long‐lived adduct becomes less important in determining the reaction products.
