Abstract
Carbon‐13 spectra of twelve chlorofluoropyridines (C5CInF5−nN), of known structure, have been assigned and an assessment has been made of the degree of additivity of substituent chemical shifts (SCS). Reasonable additivity is observed for pyridine derivatives but little regulatiry can be inferred from the spectra of perchlorinated‐diazines and ‐triazines. There is an approximately linear relationship between 13C and 19F chemical shifts.Keywords
