Rate and equilibrium constants for hydride transfer from a series of 1,3-dimethy 1-2-substituted phenyl benzimidazolines to pyridinium ion, a quinolinium ion, and a phenanthridinium ion have been evaluated. Each oxidizing agent gives a linear Br￠nsted plot with slope, α. The a values vary systematically with the spontaniety of the reactions. They are in reasonable agreement with the predictions of modified Marcus theory. Their trend is very accurately predicted, showing a parallel(Leffler-Hammond) effect. These results make a multistep mechanism, involving high energy intemediates, very unlikely.
