Abstract: The regioselective allylation of 4-silyloxy quinolinium triflates with allyltri-n-butyltin has been performed to give 2- allyl-4-silyloxy-1,2-dihydroquinolines with excellent yields. Similiar results were obtained with 4-silyloxy benzopyrylium triflates and 4-silyloxy benzothiopyrylium triflates
