摘要

在回流甲苯中，n -甲基-P，对-二苯基- n -（2-吡啶基）磷酰胺与单质硫氧化生成相应的硫化物C6H3N-2-N(CH3)(P(S)Ph2)(1)配体。1与等摩尔量的HgX2 （X = Cl， I）反应生成顺式-[HgX2{1-κ 2s，Npy}] (X = Cl（2)， I(3)）配合物。另外，副产物Ph2P（S2）。C6H4N(CH3)(H)(4)在配体1制备过程中被鉴定出来。用多核磁共振（1H， 13C和31P）和红外光谱对1-4进行了表征。用单x射线晶体学测定了1-4的分子结构。2和3是具有结构特征的新型κ2S， npy双齿配体，具有Hg（II）金属配合物。

N-methyl-P,P-diphenyl-N-(2-pyridinyl)phosphinothioic amide chelating ligand: synthesis, characterization, and X-ray structures of novel Hg(II) metal complexes

N-methyl-P,P-diphenyl-N-(2-pyridinyl)phosphinous amide was oxidized with elemental sulfur in refluxing toluene to produce the corresponding sulfide C₆H₃N-2-N(CH₃)(P(S)Ph₂) (1) ligand. The reaction of 1 with an equimolar quantity of HgX₂ (X = Cl, I) produced cis-[HgX₂{1-κ²S,N^py }] (X = Cl(2), I(3)) complexes. In addition, the side product Ph₂P(S₂).C₆H₄N(CH₃)(H) (4) was identified while ligand 1 was being prepared. 1–4 were characterized using multinuclear NMR (¹H, ¹³C, and ³¹P) and IR spectroscopy. The molecular structures of 1–4 were determined using a single X-ray crystallography. 2 and 3 are structurally characterized novel κ²S,N^py-bidentate ligands with Hg(II) metal complexes.

期刊介绍： The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
