The dichromatedithizone interaction in organic media is studied in detail at different reaction conditions. Using the EPR method it was found that the Cr( VI) reduction proceeds through different reaction mechanisms depending on the dichromate-dithizone concentration ratio. At low dithizone concentrations the redox process goes on through two consecutive two-electron steps. In the course of the Cr( VZ) reduction a relatively stable Cr(V)-dithizone complex is formed, denoted as W(2). At higher dithizone concentrations the Cr( VZ) reduction to O(V) proceeds via one-electron transfer resulting in parallel jkee radical and G(V) jormation. In this case another O(V) complex is formed denoted as W(l). It was shown that the (Y(I) further reduction proceeds through a two-electron process. The reaction mechanism including one-electron reduction of Cr(VI) to O(V) is observed for the first time.
