---The substitution of 9-(α-bromo-α-arylmethylene fluorenes by MeS- and p-TolS- ions in 80% MeCN-20% H2O is a second-order reaction. With MeS-, for the change of the α-aryl group, Hammett's ρ=1·07 in MeCN. The reaction rate decreases on increasing the water content of the medium. The reactions proceed by the AdN-E route and no competitive SN1 reaction was observed. The expected influence of the changes in the substituent, solvent, nucleophile and nucleofuge on the competition between the AdN-E and SN1 reactions was analyzed. © 1997 John Wiley & Sons, Ltd.
