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
