Abstract

Abstract The objective of this study is to test the suitability of the extended Hammett–Brown equation, log (k XX/k HH)= ρ+ Σσ+, in depicting satisfactorily additive effects of electronegative atom-bearing substituents, which are known to possess diverse and multicomponent influences on the side chain reactions of polysubstituted benzenes. The equation has been used to correlate, for the first time, the additive effect of substituents in ...
