摘要：
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 sigma-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 10(9) dm(3) mol(-1) s(-1). Intrinsic reactivities of carbanions in sigma-adduct forming transfer reactions are compared.
