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

allyl derivatives, 2-(2-methoxyethyl)-3-methyl-2-cyclohexenyl p-nitrobenzoate was solvolyzed in various solvents including fluorinated alcohols. Its solvolysis rate is slower than that of the 2-butyl analog . This rate retardation can be explained by an electron-withdrawing inductive effect of methoxy group. The secondary α-deuterium isotope effect of ester is normal in all the solvents investigated.
