Dithiocarbamate iron complexe

Trivalent iron dithiocarbamate complexes have been extensively studied, because of the existence of "spin equilibria in these complexes. Table II outlines the tris(l,l-dithiocarbamate) iron(III) complexes and, some of their physical properties. 

The traditional copper fungicides are in fact inorganic copper coordination compounds The still most important group of organic protectant fungicides, the dithiocarbamates, are applied in the form of their metal-coordination compounds. Dimethyldithiocarbamate as the iron complex ferbam and the zinc complex ziram, ethylenebisthiocarbamate as the zinc complex zineb and the manganese complex maneb.

Vinyl acetate is the monomer that has required significant efforts in order to achieve LRP. The first successfiil attempt was using RAFT with xanthates as a RAFT agent (also known as MADIX). At a later stage it turned out that certain dithiocarbamates also were able to induce LRP of vinyl acetate. Of all the attempts to pol5unerize VAc using ATRP, only specific iron complexes used by Sawamoto and co-workers were claimed to be successful (61). However, the PDIs they claimed were relatively large compared to other monomer/catalyst combinations. 

In this paper we shall extend our earlier interpretation of the redox results to the nmr data for the N - CH2 protons in tris(N,N-diethyldithiocarbamato) iron(III). We shall show that the solvent dependence of the nmr shifts can be interpreted as arising from solvent interactions with the iron(III) dithiocarbamate system. Although the solvent interactions are small compared with the electronic interactions within the transition metal iron complex the effect is marked since in these cases for the d iron system there are low lying electronic states where the energy separation is sensitive to small changes in the crystal field environment of the transition metal ion.
