摘要：

The reactions of nine different mono-para-substituted triphenylaminium cations produced by oxidation of the parent amines by Cu(II) in acetonitrile have been studied. The cation radicals undergo apparent second-order coupling reactions giving rate constants ranging from 4.4 × 103 to 8.8 × 10-2 M-1 s-1. These values correlate well with rate constants for these reactions previously determined by chronoamperometric measurements and their determination should better establish the reliability of electrochemical methods for studying similar systems. © 1979 American Chemical Society.
