Abstract
The bimolecular reactions of azide, 2-iodosobenzoate, and acetohydroxamate ions and methoxyamine nucleophiles with substituted phenyl acetates possess Yukawa-Tsuno type correlations with substantial resonance interaction. The rate constants for hydroperoxide ion and the oxyanion of N,N-diethylhydroxylamine obey simple Hammett equations. The reactivities of azide, acetohydroxamate, hydroperoxide, and 2-iodosobenzoate ion nucleophiles exhibit modest alpha -effects when the reactivity in substitution at 4-nitrophenyl acetate is compared with that of phenoxide ions of similar pKa values. The N,N-diethylhydroxylamine oxyanion is less reactive than its phenoxide ion analogue due to steric requirements, and the reactivities of the anionic nucleophiles exhibit changes in effective charge on the leaving oxygen similar to those for regular nucleophiles of similar pKa. Methoxyamine possesses only a small enhancement compared with the reactivity of a normal primary amine of similar pKa.Key words: alpha -effect, nucleophile, Yukawa-Tsuno, Leffler, Hammett, phenyl ester, effective charge, Brønsted.
