Abstract

A non-aqueous electrochemical study of dithizone, H2Dz, 1, is compared with the chemical oxidation and reduction profile of this versatile ligand. Chemical oxidation of 1 by I2 initially leads to an isolatable disulfide-bridged species,(HDz) 2, 22, but ultimately monomeric dehydrodithizone, Dz, 3, is formed. Electrochemically, in CH2Cl2/0.1 moldm− 3 [N (nBu) 4][B (C6F5) 4], two oxidation processes are observed for 1. Evidence of the electrochemical ...
