摘要：

The thermal behaviour of the dithiocarbamic ester complexes [M(MeS2CNMe2)X2] (M = Pd or Pt; X = Cl or Br) and [Pd(MeS2CNEt2)Cl2] has been examined up to 1100° C. The first decomposition step involves MeX release to form the corresponding species [M(S2CNMe2)X]n and [Pd(S2CNEt2)Cl]n. The degradation intermediates have been isolated and characterized by elemental analyses and IR and NMR (1H and 13C) spectra. Their possible structure is discussed and correlated with the properties of the starting dithiocarbamic ester adducts. On heating, the mixed complexes [Pt(S2CNEt2)(MeS2CNR2)Cl] (R = Me or Et) undergo an analogous S-demethylation process, MeCl being evolved at temperatures lower than those of the same process for the [Pt(MeS2CNMe2)X2] species. © 1990.
