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.
