    Abstract

    The dithioester (CH2)4NCS2CH3 (PyDTM, 1-pyrrolidinecarbodithioate methyl ester) has been prepared by reaction of the parent ammonium salt View the MathML sourceNH4PyDT(PyDT=(CH2)4NCS2-) with methyl iodide in water/ethanol. The reaction of PyDTM with PdCl2 allowed to synthesize either [PdCl2(PyDTM)], in which the ligand is chelated by both sulfur atoms, or [PdCl2(PyDTM)2], in which the ligand acts as monodentate through the thiocarbonyl sulfur. Thermal degradation of [PdCl2(PyDTM)] yielded the [PdCl(PyDT)]n species as an intermediate, which, in the presence of donors as chloride ions or dimethyl sulfoxide (DMSO), gave the complexes [PdCl(PyDT)(DMSO)] and NR4[PdCl2(PyDT)]. Moreover, PyDTM was found to react with various [PdCl(dithiocarbamato)]n intermediates to form the mixed species [PdCl(dithiocarbamato)(PyDTM)], whose thermal degradation yielded the [Pd(dithiocarbamato)(PyDT)] complexes. The behaviour of the prepared compounds in either solution or solid phase has been described on the basis of IR and proton NMR spectra and thermogravimetric analysis (TG and DTA).
