Abstract Reactivities of acridine derivatives (10-benzylacridinium ion, 1a+, 10- methylacridinium ion, 1b+, and 10-methyl-9-phenylacridinium ion, 1c+) have been compared quantitatively for hydride transfer reactions with 1, 3-dimethyl-2-substituted phenylbenzimidazoline compounds, 2Ha–h. Reactions were monitored spectrophotometrically in a solvent consisting of four parts of 2-propanol to one part of ...
