Abstract
Carbon-13 magnetic resonance shifts were determined for six families of 1,4-disubstituted benzenes. Linear least-squares correlations between the internal shifts of the families suggest an additivity relationship for 13C substituent effects at all four nonidentical ring carbons and at the α position when one of the substituents has a central carbon. The correlation of 1H and 13C shifts for these compounds is also linear, implying that the additivity relationships derived in a previous 1H study can be generalized to 13C.
