The relative changes in the rate constants are strictly bound to changes in the equilibrium constant of complex formation between the sulfonate and the Grignard reagent by replacement of a donor THF molecule as well as the transfer rate of the carbanion to the sulfonate in the complex. These results provide another support for asynchronous SNa mechanism comprising a four-center transition state mechanism.
