Electron Transfer Reactivity in Conjugated Azo Aromatic Dye

Abstract

Chemical reactivity of a donor-acceptor molecule containing azo moiety in two different oxidation states was explored. The chemical reduction of the compound with Zn/H₂O produced a new compound in moderate yield (ca. 35%) from an unprecedented chemical transformation that is associated with –N–N– bond cleavage process. The intense blue color of the starting compound had faded away slowly as the reaction proceeded. The compound was characterized by different spectroscopic techniques, and X-ray data. One plausible mechanism was proposed in support of the formation of the compound.
