Rate and equilibrium measurements are reported for the reactions in methanol of carbanions derived from 12 ring-substituted benzyl cyanides with 1,3,5-trinitrobenzene to give ?-adducts.Some data for reaction of the carbanions with 4-nitrobenzofuroxan were also measured.With increasing carbanion reactivity, rate constants approach a limit of just below 109 dm3 mol-1 s-1.Intrinsic reactivities of carbanions in ?-adduct forming reactions and in proton transfer reactions are compared.
