Group 16 metals, dithiocarbamate complexes

Evolved gas applications are widespread and diverse. Coordination chemistry has been considerably enhanced by thermal analysis studies of a wide range of metal complexes. The emphasis of these studies has been to derive thermal decomposition mechanisms for such metal complexes. Prior to the development of EGA, such reported mechanisms were suspect because the volatile decomposition products and the solid intermediates were, in general, not identified directly but characterized indirectly on the basis of mass loss data. This procedure is flawed when multiple gaseous decomposition products and nonstoichiometiic intermediates are involved. The thermal analysis of one such group of metal complexes, the metal dithiocarbamates, has been extensively studied and reviewed by Hill and Magee and these are definitive studies in this field. [Pg.3012]

Main group dithiocarbamate complexes are generally prepared by reaction of the appropriate metal halide with the parent (hydrated) group 1 (I A) metal or ammonium dithiocarbamate salt. Few dithiocarbamate complexes of boron and aluminum have therefore been reported aluminum and boron halides are susceptible to hydrolysis, and hydroxide substitution is generally unfavorable. [Pg.4]

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). [Pg.101]

The dithiocarbamate chemistry of the group 12 (11B) elements is well developed, with applications in the areas of analytical chemistry, agriculture, rubber vulcanization, and as molecular precursors to metal sulfides. As expected, their chemistry is constrained to the - -2 oxidation state and it is the bis(dithiocarbamate) complexes [M(S2CNR2)2], which are the most common, being first prepared in 1907 (2). [Pg.429]
