Özet
The C-S coupling reactions of aryl benzenesulfonates with phenylmagnesium bromide in THF:toluene (7:10) at 90 A degrees C have been studied. A Hammett-type kinetic study of the leaving group effect of aryloxy groups provides a conclusive support for a two step addition-elimination mechanism in which C-S bond formation is rate determining step.
