- 中文摘要: Treatment of Pd(PPh3)4 with phenylchlorothionoformate, PhOC(S)Cl, in dichloromethane at -20 °C produces the phenyloxythiocarbonyl complex [Pd(PPh3)2{η1-C(S)Oph}(Cl)], 1. The 31P{1H} NMR spectrum of 1 shows the dissociation of either the chloride or the triphenylphosphine ligand to form complex [Pd(PPh3)2(η2-SCOPh)][Cl], 2 or the dipalladium complex [Pd(PPh3)Cl]2(μ,η2-SCOPh)2, 3. Continuous stirring of the dichloromethane solution of 1 at room temperature for 4 h forms the dipalladinum complex [Pd(PPh3)Cl]2(μ,η2-SCOPh)2, 3 as the final product. Respective reactions of 1 and Et2NCS2Na or dppa {bis(diphenylphosphino)amine} gives complex [Pd(PPh3){η1-C(S)Oph}(η2-S2CNEt2)], 4 or [Pd(PPh3){η1-C(S)Oph}(η2-dppa)][Cl], 5. Complex 1 is determined by single-crystal X-ray diffraction and crystallized in the monoclinic space group P21 with Z = 4. The cell dimensions of 1 are as follows: a = 9.5613(1) A, b = 33.6732(3) A, c =12.2979(1) A.
