PdCl_2·2H_2O与2equiv. 4-(三甲基铵基)苯硫酚(Tab)(由TabHPF 6和Et 3 N在MeOH中的混合物原位制备)和七个膦配体:PPh3,1,1-bis(二苯基膦基)甲烷(dppm),1,2-双1,3-双(二苯基膦基)乙烷(dppe)1,4-双(二苯基膦基)丙烷(dppp)(二苯基膦基)丁烷(dppb),N,N,N′,N′-四(二苯基膦基甲基)乙二胺(dppeda)和1,4-N,N,N′,N′-四(二苯基膦基甲基)苯二胺(dpppda)合成了一类单核和双核的Pd(II)/Tab/膦配合物[Pd_2(PPh_3)_2(Tab)_2(μ-Tab)_2](PF_6)_4(1),[Pd2(dppm)2(Tab)2(μ-Tab)](PF 6)4(2)、[Pd2(dppb)(Tab)2(μ-Tab)2] Cl 4(3)、[PdL(Tab)2](PF 6)2(4:L=dppe; 5:L=dppp)和{[PdL(Tab)2]2} Cl 4(6:L=dppeda; 7:L=dpppda)。通过元素分析、红外光谱、紫外-可见光谱、核磁共振氢谱、电喷雾质谱和单晶X-射线衍射等手段对化合物进行了表征。在1-7的结构中,每个Pd(II)采用近似正方形平面配位几何构型。结果提供了一个有趣的洞察钯(II)/硫醇/膦配合物的化学。
Reactions of PdCl2·2H2O with 2equiv. of 4-(trimethylammonio)benzenethiolate (Tab) (prepared in situ from a mixture of TabHPF6and Et3N in MeOH) and seven phosphine ligands: PPh3, 1,1-bis(diphenylphosphino)methane (dppm), 1,2-bis(diphenylphosphino)ethane (dppe), 1,3-bis(diphenylphosphino)propane (dppp), 1,4-bis(diphenylphosphino)butane (dppb), N,N,N′,N′-tetra(diphenylphosphanylmethyl)ethylene diamine (dppeda), and 1,4-N,N,N′,N′-tetra(diphenylphosphanylmethyl)benzene diamine (dpppda), afforded a family of mononuclear and dinuclear Pd(II)/Tab/phosphine complexes, [Pd2(PPh3)2(Tab)2(μ-Tab)2](PF6)4(1), [Pd2(dppm)2(Tab)2(μ-Tab)](PF6)4(2), [Pd2(dppb)(Tab)2(μ-Tab)2]Cl4(3), [PdL(Tab)2](PF6)2(4: L=dppe; 5: L=dppp) and {[PdL(Tab)2]2}Cl4(6: L=dppeda; 7: L=dpppda). These compounds were characterized by elemental analysis, IR spectra, UV–Vis spectra,1H and31P{1H} NMR, electrospray ionization (ESI) mass spectra and single-crystal X-ray diffraction. In the structure of 1–7, each Pd(II) adopt an approximate square planar coordination geometry. The results provide an interesting insight into the chemistry of palladium(II)/thiolate/phosphine complexes.
