Cu(II) Mediated Generation and Spectroscopic Study of the Tris(4-anisyl)amine Radical Cation and Dication. Unusually Shielded Chemical Shifts in the Dication

Abstract

The reaction of tris(4-anisyl)amine (TAA) with Cu(2+) ion leading to formation of the TAA radical cation and dication is described. Spectroscopic studies confirm the formation of the radical cation and dication. (1)H and (13)C NMR spectral studies reveal interesting structural features of the dication.
