EnglishThe non-additivity in the 13C substituent chemical shifts (SCS) of 1,3-and 1,4-disubstituted benzenes has been studied using multivariate data analytical methods. Most of the non-additivity is systematic and can be predicted with high accuracy (0.2 ppm) from carbon shifts of monosubstituted benzenes. This means that no additional substituent effects are needed and that the non-additivity contributions of the SCS are clustered in the same way as previously noticed for 13C SCS in monosubstituted benzenes.
