  铜（I）和银（I）的三苄基膦硫化物配合物的结构研究

  摘要：

  三苄基膦硫醚（SPBn 3）与[Cu（CH 3 CN）4 ] PF 6以2：1的比例反应生成[Cu（CH 3 CN）（SPBn 3）2 ] PF 6，而与[Ag（CH 3 CN） ）4 ] PF 6以相同的比例形成[Ag 2（SPBn 3）3 ]（PF 6）2。Cu（I）配合物的晶体结构表明它包含离散的3配位[Cu（CH 3 CN）（SPBn 3）2 ] +阳离子和[PF 6] -阴离子，其中Cu原子位于由两个配位的硫原子和来自配位乙腈分子的氮形成的平面中。Ag配合物是双核物质，一个银原子为3-配位，另一个为4-配位。每个SPBN 3分子形成的Ag-Cη 1 -键与从而阻断的进一步SPBN协调的芳香环中的一个3配体。两个银中心通过桥连的硫和与相同的三苄基膦硫醚的芳香环中的碳的弱相互作用而连接。

• Mechanism of biphosphine disulphide formation in reactions of thiophosphoryl and phosphonothioic halides with Grignard reagents
  作者：P. C. Crofts、I. S. Fox

  DOI：10.1039/j29680001416

  日期：——

  The factors favouring formation of biphosphine disulphides are identified and evidence is presented (a) for attack by the Grignard reagent on chlorine, and (b) that phosphorus–phosphorus bond formation does not occur when two organic groups are attached to phosphorus. A mechanism is proposed, involving simultaneous removal of two halogen atoms from the thiophosphorus halide yielding a phosphinidene

  确定了有助于形成双膦二硫化物的因素，并提供了证据（a）格氏试剂对氯的攻击，以及（b）当两个有机基团与磷连接时不会发生磷-磷键的形成。的机构，提出，涉及同时除去从该硫代含磷的两个卤素原子的卤化物产生一个亚膦硫化物，R-P S，其形成磷-磷键或者经由硫代磷卤化镁或通过插入磷-卤素键。该机理令人满意地解释了对可能涉及的有机基团的限制以及来自烷基溴化镁的双膦二硫化物比烷基氯化镁的高收率。

  Aviation fuel formulations receive many benefits when a manganese-containing additive is incorporated in that composition. However, to the extent that the use of a manganese-containing compound may result in the formation of engine deposits during combustion, it is beneficial to further provide a scavenger compound to the fuel composition. This scavenger compound may include a phosphorus-containing compound, an organobromide compounds, and/or a tricarbonyl compound.

  当航空燃料配方中加入含锰添加剂时，会带来许多好处。然而，由于使用含锰化合物可能会导致发动机在燃烧过程中形成沉积物，因此在燃料组合物中进一步加入一种清除剂化合物是有益的。这种清除剂化合物可包括含磷化合物、有机溴化物和/或三羰基化合物。

• Non-toxic corrosion-protection pigments based on manganese

  公开（公告）日：2004-01-22

  Corrosion-inhibiting pigments based on manganese are described that contain a trivalent or tetravalent manganese/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent manganese ion to form a compound that is sparingly soluble, exhibits low solubility, or is insoluble in water, depending upon the intended usage. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent manganese during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Manganese/valence stabilizer combinations are chosen based on the well-founded principles of manganese coordination chemistry. Many manganese-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium or tetravalent lead systems. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  以锰为基础的缓蚀颜料含有三价或四价锰/价稳定剂复合物。一种无机或有机材料可用于稳定三价或四价锰离子，从而形成一种可少量溶解、溶解度低或不溶于水的化合物，具体取决于预期用途。选择特定的稳定剂是为了控制三价锰或四价锰在遇水时的释放率，并调整粉末在所选粘合剂体系中用作颜料时的相容性。稳定剂还可以改变成型粉末的加工和处理特性。锰/价稳定剂组合的选择是基于锰配位化学的基本原理。文中介绍了许多锰价稳定剂组合，其性能与传统的六价铬或四价铅体系相当。需要强调的是，提供本摘要是为了符合要求提供摘要的规则，以便检索者或其他读者快速确定技术公开的主题。提交本摘要的前提是，本摘要不用于解释或限制权利要求的范围或含义。
