A systematic investigation of solvolyticreactivities of allylic and benzylic nicotinates and their N-methylated derivatives in 80% EtOH, 97% TFE and 97% HFIP was undertaken. The nicotinates in 97% HFIP are slightly more reactive than the corresponding p-nitrobenzoates, whereas the ratio of these reactivities is inverse in 80% EtOH and 97% TFE. This observation was explained by the stronger hydrogen

of alkoxy group participation in the solvolysis of allylic p-nitrobenzoates with an ω-alkoxyalkyl side-chain at C-2 center was studied. In 80% EtOH the solvolysisrates, secondary α-deuterium isotope effects, and the product composition show that, contrary to π-participation, neighboring oxygen interacts to a certain degree in the ratedetermining step of solvolysis when a six-membered oxygen-containing
