Abstract

CAKIR, Semiha; BICER, Ender; ODABASOGLU, Mustafa  and  ALBAYRAK, Çigdem. Electrochemical and spectroscopic study of 4-(Phenyldiazenyl)-2-{[tris-(hydroxymethyl)methyl] aminomethylene}cyclohexa-3,5-dien-1(2H)-one: mechanism of the azo and imine electroreduction. J. Braz. Chem. Soc. [online]. 2005, vol.16, n.4, pp. 711-717. ISSN 0103-5053.  http://dx.doi.org/10.1590/S0103-50532005000500005.

Newly synthesized 4-(phenyldiazenyl)-2-{[tris(hydroxymethyl)methyl]aminomethylene} cyclohexa-3,5-dien-1(2H)-one was characterized by elemental analysis, FT-IR, NMR, electronic spectra, voltammetry. Tautomeric equilibrium of 4-(phenyldiazenyl)-2-{[tris(hydroxymethyl) methyl]aminomethylene}cyclohexa-3,5-dien-1(2H)-one in DMSOd is supported by 1H NMR data. The nature of electrochemical process of 4-(phenyldiazenyl)-2-{[tris(hydroxymethyl) methyl]aminomethylene}cyclohexa-3,5-dien-1(2H)-one in Britton-Robinson buffer (pH 2-9) was studied on the HMDE by square-wave (SWV), adsorptive stripping square-wave (AdSWV) and cyclic voltammetry (CV). The electrochemical parameters (Ip/Ep, Ip/v, Ip/pH, Ip/tacc) of the compound were determined.

Keywords : 4-(phenyldiazenyl)-2-{[tris(hydroxymethyl)methyl]aminomethylene}cyclohexa-3,5 -dien-1(2H)-one; FT-IR; electronic spectra; voltammetry.
