摘要:
Reactions of Na2[PdCl4] with one equivalent and two equivalents of bis(benzylthio)methane (btm) yield trans-[PdCl2(mu-btm)]n (1) and trans-[PdCl2(btm-S)2] (2), respectively. Treatment of 2 with [PdCl2(NCMe)2] gives the face-to-face type palladium(II) complex, trans-[Pd2Cl4(mu-btm)2] (3), whereas the reaction of 2 with [Pd(dba)2] (dba = dibenzylideneacetone) produces the side-by-side type palladium(I) complex, [Pd2Cl2(mu-btm)2] (4). Treatment of 4 with dimethyl acetylenedicarboxylate gives the A-frame type complex [Pd2Cl2{mu-C2(CO2Me)2}(mu-btm)2].1/2CH2Cl2 (5). The complexes obtained in this study were characterized by elemental analysis, IR and NMR spectroscopy.
