Abstract
1. A study has been made of the gas-phase reaction of C4H9+, C3H7+, and C3H3+ carbocations with sterically hindered phenols. 2. Alkylation through the benzene ringoccurs when the ortho and para positions relative to the hydroxyl group are free. 3. The carbocations associate with the CN, CH2CN, CHO, and COCH3 groups when these are present as benzene-ring substituents. 4. The intensity of alkylation and dealkylation in these phenols is dependent on the temperature.
