  acid-catalyzed exchange reaction of trithioorthoesters with thiols. We found that trithioorthoester exchange occurs readily in various solvents in the presence of stoichiometric amounts of strong Bronsted acids or catalytic amounts of certain Lewis acids. The scope of the exchange reaction was explored with various substrates, and conditions were identified that permit clean metathesis reactions between two

  为了扩展动态共价和系统化学的工具箱，我们研究了三硫代原酸酯与硫醇的酸催化交换反应。我们发现在化学计量量的强布朗斯台德酸或催化量的某些路易斯酸存在下，三硫代原酸酯交换在各种溶剂中很容易发生。用各种底物探索了交换反应的范围，并确定了允许两种不同三硫代原酸酯之间发生清洁复分解反应的条件。S,S,S-原酸酯交换相对于 O,O,O-原酸酯交换的一个明显优势是交换反应可以在动力学上胜过水解，从而使该过程对残留水分不那么敏感。

  Pyridine N-oxides bearing electron-donating substituents (III) are efficient catalysts for rearrangement of O-alkyl S-methyl dithiocarbonates (xanthates) (I) to the corresponding S-alkyl S-methyl dithiocarbonates (dithiolcarbonates) (II). Of the catalysts tested, 4-piperidinopyridine N-oxide (IIIh) is the best from the viewpoints of catalytic activity and solubility in I. Heating of I in the presence of catalytic amounts (0.02-0.05 molar eq) of IIIh gave II together with the symmetric S, S-dialkyl and S, S-dimethyl dithiocarbonates in good yields. The catalytic behavior of donor-substituted pyridine N-oxides is discussed on the basis of kinetic and molecular orbital calculation data. The complete calculation of the perturbation equation on the initial stage of the reaction was consistent with the experimentally observed activity of the catalysts.

  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。

  A corrosion-inhibiting pigment comprising a rare earth element and a valence stabilizer combinded to form a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, terbium, praseodymium, or a combination thereof, and at least one rare earth element is in the tetravalent oxidation state. An inorganic or organic material is used to stabilize the tetravalent rare earth ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of tetravalent cerium, terbium, or praseodymium 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. Many rare earth-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.
