  新型混合配体 Pt(II) 配合物：顺式和反式 Pt(R2SO)(吡嗪)Cl2 的合成、多核磁共振和晶体结构

  摘要：

  由K[Pt(R2SO)Cl3]与吡嗪的水溶液反应合成了一种新型的混合配体Pt(II)配合物Pt(R2SO)(pyrazine)Cl2。这些化合物主要通过红外光谱和多核磁共振光谱（1H、13C 和 195Pt）和晶体学进行表征。研究了含有二甲基亚砜、四亚甲基亚砜、二正丙基亚砜、二正丁基亚砜、二苄基亚砜和二苯基亚砜的化合物。红外光谱表明二正丙基亚砜配合物为顺式几何结构，其他化合物为反式几何结构。配合物的 195Pt NMR 共振在Δ≤3042 和Δ≤3121 ppm 之间观察到，其中二苯亚砜配合物的场强高于其他配合物。观察到 DMSO 化合物的吡嗪 3J(195Pt-1H) 偶联常数 (33 Hz)，表明存在反式几何。未检测到 J(195Pt-13C) 偶联。反式-Pt(四亚甲基亚砜)(吡嗪)Cl2和顺式-Pt(二正丙基亚砜)(吡嗪)Cl2的晶体结构...

  A new type of pyrazine-bridged platinum(II) complexes, trans,trans-Pt(R2SO)Cl-2(mu-pyrazine)Pt(R2SO)Cl-2 was synthesized and characterized mainly by IR and multinuclear magnetic resonance spectroscopies (H-1, C-13 and Pt-195) and by crystallographic methods. Compounds with dimethylsulfoxide, tetramethylenesulfoxide, di-n-propylsulfoxide, di-n-butylsulfoxide, dibenzylsulfoxide and diphenylsulfoxide were prepared. The compounds were synthezised in good yields from the aqueous reaction of K[Pt(RSO)Cl-3] with pyrazine. IR spectroscopy showed only one v(Pt-Cl) band suggesting trans isomers. The Pt-195 NMR signals of the dimeric species were observed between -3041 and -3113 ppm. The resonance of the diphenylsulfoxide complex was found at higher fields than the other compounds. In H-1 NMR, the pyrazine protons are more deshielded (ave. 0.52 ppm) than in free pyrazine. The coupling constants with the pyrazine protons (3)J(Pt-195-H-1) are between 28 and 35 Hz. The crystal structures of three pyrazine-bridged dimers. trans-Pt(R2SO)Cl-2}(2)(mu-pyrazine) were studied by X-ray diffraction methods. The results confirmed the trans,trans configuration of the compounds. All the molecules contain an inversion centre. (C) 2004 Published by Elsevier B.V.
