Abstract	The rates for the reaction of (Z)-phenacyl (X)-benzenesulfonates with (Y)-pyridines in acetone were measured by an electrical conductivity method at 1-2000 bars and 45 ℃. The magnitudes of the Hammett reaction constants, ρX, ρY and ρZ, represent the degree of Nu-C bond formation and that of C-L bond breaking. The magnitude of correlation interaction term ρij can be used to determine the structure of the transition state (TS) for the SN reaction. As the pressure is increased, the Hammett reaction constants, ρX,
