The dependence of the ρ values of electrophilic substitutions upon the nature of the aromatic substrate: trifluoroacetylation of substituted furans, thiophens, and pyrroles

Abstract

ρ Constants for electrophilic substitutions vary with the nature of the aromatic reference substrate, as shown by an examination of the data available in the literature and by a comparative study of substituent effects in the trifluoroacetylation of furan, thiophen, and pyrrole nuclei. The differences in sensitivities to structural changes are discussed in term of different positions of the transition states along the reaction co-ordinates.
