Oxidation states dithiocarbamate synthesis

Electrochemical studies by cyclic voltametry (351) established a scheme for these compounds not unlike the one observed with the dithiocarbamate analogues (Eq. 12). Not unexpectedly, and in accord with the ability of R2Dtc ligands to stabilize higher oxidation states, the two-electron oxidation found with the Mo(IV)(R2Dtc)4 complexes is not observed in the Mo(lV)(RSXant)4 compounds. Instead, a two-electron reduction is observed in the latter, with the formation of a formally Mo(II)-containing monomer (Eq. 12). The synthesis and... 

Dithiocarbamates stabilize copper in the +1, +2, and +3 oxidation states, with copper(II) bis(dithiocarbamate) complexes, first reported by Delepine (2) being most common. Later, Cambi and Coriselli (1662) detailed the synthesis of a range of these and also copper(I) dithiocarbamate complexes, and in the 1960s copper(III) complexes were prepared (1663). Over the past 20 years, some significant new developments have been made and a wide range of applications has been established.
