• Thermal analysis of 2-oxocyclopentanedithiocarboxylato complexes of iron(iii), copper(ii) and zinc(ii) containing pyridine or morpholine as the second ligand

  A series of ternary complexes of the types M2L′2L″2;ML′2L″2 (M=Fe, Cu, Zn; L′=2-oxocyclopentane dithiocarboxylate; L″=pyridine, morpholine) and CuL′2H2O was prepared afresh. Except the iron complex, all are dimer and complexation is through the dithio moiety of the ligand L′. Their thermal decomposition was carried out in air at heating rate 10°C min−1 and it revealed that the dehydration of the aqua complex follows the same path as the carboxylates and the pyridine complexes have the tendency to follow one-step decomposition. The copper complexes are less thermally stable. The overall thermal stability of the 2-oxocyclopentanedithiocarboxylato complexes of the three metals with the volatile ligands was found to be in the order: (CuLmorph)2< CuL2H2O<(CuLpy)2<(ZnLmorph)2<(ZnLpy)2

  一系列三元复合物，类型为 M2L′2L″2、ML′2L″2（M=Fe、Cu、Zn；L′=2-氧环戊二硫羧酸盐；L″=吡啶、吗啉）和 CuL′2 ，被新鲜制备。除铁复合物外，所有复合物均为二聚体，配体 L′ 通过二硫部分进行配位。在加热速率为 10°C min−1 的空气中进行热分解，结果表明水合物复合物脱水过程与羧酸盐复合物相同，而吡啶复合物倾向于一步分解。铜复合物的热稳定性较低。三种金属与挥发性配体形成的 2-氧环戊二硫羧酸盐复合物整体热稳定性顺序为：(CuLmorph)2 < CuL2H2O < (CuLpy)2 < (ZnLmorph)2 < (ZnLpy)2。

  Exposure of 3-oxo dithioic acids to a solution of polysulfanes in liquid hydrogen sulfide gives 3H-1,2-dithiole-3-thiones in yields varying from poor to excellent. The method tolerates the presence of functional groups which are problematical for other methods of synthesis.
