## Carbon -13 NMR spectra are reported for 69 substituted methyl benzoates in deuteriochloroform or in its mixture with dimethyl sulphoxide-d, . The substituent-induced chemical shifts (SCS) of the CO carbon correlate poorly with dual substituent parameters (DSP) in all possible modifications, and

There are many literature examples correlating C-13 n.m.r. substituent chemical shifts in substituted benzenes with Bsamett substituent constants.' The direction of these substituent chemical shifts has been logically explained in terms of substituent electronic properties; the electron donors resul
