Abstract

Rate and equilibrium constants for hydride transfer from a series of 1, 3-dimethyl-2- substituted phenylbenzimidazolines to a pyridinium ion, a quinolinium ion, and a phenanthridinium ion have been evaluated. Each oxidizing agent gives a linear Brønsted plot with slope, α. The α values vary systematically with the spontaniety of the reactions. They are in reasonable agreement with the predictions of modified Marcus theory. Their ...
