Abstract

Abstract The kinetics of the reactions of substituted ethyl arylacetates with quinone methides and structurally related diethyl benzylidenemalonates have been studied in DMSO. The second-order rate constants (lg k 2) correlated linearly with the electrophilicities E according to the linear free-energy relationship lg k 2= s N (N+ E), allowing us to determine the nucleophilicity parameters N and s N for these anions. The nucleophilic reactivities of the ...
