Abstract
- Eight palladium(II) pyrrolidine dithiocarbamate complexes were prepared and fully characterized. Reactions of the dimeric cyclopalladated complexes, [Pd(ppy)(μ-Cl)]2 (ppyH= phenylpyridine) or [Pd(N-BAZ)(μ-Cl)]2 (N-BAZH = N,N-dimethylbenzylamine) with two moles equivalent of ammonium pyrrolidine dithiocarbamate NH4(PyDT) afford [Pd(PyDT)(ppy)] and [Pd(κ2-PyDT)(N-BAZ)] in good yield (91 and 71 % respectively). A crystal structure of [Pd(PyDT)(ppy)] reveals that the PyDT ligand is bonded as a bidentate chelate. Reaction of trans-[PdCl2(DMSO)2] with sodium benzisothiazolinate (NaBit), followed by NH4(PyDT) afford Na[Pd(PyDT)(N-Bit)2]. Diphosphine adducts [Pd(PyDT)2{Ph2P(CH2)nPPh2}] {n = 2-4 or (CH2)n = (C5H4)2Fe}, can be prepared in good yield upon addition of the diphosphine to [Pd(PyDT)2]. Reaction of trans-[PdCl2(PPh3)2] with sodium saccharinate (Nasac) followed by NH4(PyDT) afford trans-[Pd(PyDT)(N-sac)(PPh3)2]. The prepared complexes were characterized by elemental analysis, i.r., 1H, 31P nmr spectroscopic data and conductivity measurements.
