Dear All:
10-15 years ago I saw a paper in J. Org. Chem. (or another journal - I don't
remember which one) on 13C chemical shifts of polysubstituted benzenes. It
contained empirical parameters for the calculations of chemical shifts in
substituted benzenes for hundreds (!) of different substituents. I kept a copy
of the paper but unfortunately lost it. Can anybody help me and send the
reference?
Alex
