Group 10 metals, dithiocarbamate nickel

Later work on the reactions of nickel xanthate complexes, [Ni(S2COR )2], with secondary amines revealed the formation of thiourethanes, R2NC(S)OR, together with nickel bis(dithiocarbamate) complexes (Fig. 26). Both are product of nucleophilic attack of the amine at the -hybridized carbon, the difference between the two pathways being whether the alkoxide or metal-sulfide moieties act as the leaving group (225).
