Synthesis and Spectral Characterization of a New Class of Heterocyclic Analogues of Crystal Violet Dyes
摘要:
Deep purple: By the transformation of readily available N,N-disubstituted 2-aminothiophenes and 2-aminothiazoles into heterocyclic analogues of Crystal Violet, such as, tris(2-dimethylamino-5-thienyl)methinium prechlorate (cation shown), the series of dyes derived from these heterocyclic structural units as the important chromophoric component is significantly extended and a gap in the class of heteroanalogous triphenylmethane dyes has been closed.

The Interplay of Thio(seleno)amide/Vinylogous Thio(seleno)amide “Resonance” and the Anisotropic Effect of Thiocarbonyl and Selenocarbonyl Functional Groups
spectra assigned. Both the NMR data and the results of theoretical calculations at the abinitio level of theory were employed to elucidate the adopted structures of the compounds in terms of E/Z isomerism and s-cis/s-trans configuration. In the case of the asymmetrically N(Me)Ph-substituted compounds, abinitio GIAO-calculated ringcurrent effects of the N-phenyl group were applied to successfully determine
