Abstract

The kinetics of oxidation of a series of eight N-(substituted benzyl) acridans (3, NBA's) by 1, 4-benzoquinone (BQ), p-chloranil (CA), 2, 3-dicyano-1, 4-benzoquinone (DCBQ), 7, 7, 8, 8- tetracyanoquinodimethane (TCNQ), and tetracyanoethylene (TCNE) in acetonitrile (AN) and by BQ in 50: 50 (v/v) AN-water were measured at 25° C. Equilibrium constants for pseudobase formation,, from the corresponding acridinium ions (4) were measured in ...
